It is very important to know which chapters to prioritize. This plan should be prepared according to the weightage of each chapter based on the previous year's weightage. Our experts have prepared the JEE Mains chapterwise weightage of all subjects based on the total number of questions asked from them in the last 10 years.

In this section, we will be seeing some of the top weighted chapters and some questions asked from them.

This table has the most important chapters of JEE Main Physics PYQ chapterwise PDF according to the last 10 years' JEE Main question papers.

JEE Main Physics PYQ

Some questions have been listed below from the top chapters:

1. Optics

Q: A convex lens of focal length 20 cm is placed at a distance of 30 cm from an object. Find the position and nature of the image formed.

Solution: Using the lens formula,

As we know,

$
\frac{1}{f}=\frac{1}{v}-\frac{1}{u}
$

Put the values in the lens formula,

$
\begin{gathered}
\frac{1}{20}=\frac{1}{v}-\frac{1}{(-30)} \\
\frac{1}{v}=\frac{1}{20}-\frac{1}{30}=\frac{1}{60} \\
v=60 \mathrm{~cm}
\end{gathered}
$

The image is real, inverted, and formed 60 cm on the other side of the lens.

2. Electrostatics

Q: Two equal point charges +q are placed at a distance d apart. Find the electric field at the midpoint of the line joining them.

Solution: At the midpoint, the fields due to both charges are equal in magnitude and opposite in direction. Hence,

E net = 0

3. Properties of Solids & Liquids

Q:A sample of a liquid is kept at 1 atm . It is compressed to 5 atm , which leads to a change in volume of $0.8 \mathrm{~cm}^3$. If the bulk modulus of the liquid is 2 GPa , the initial volume of the liquid was $\_\_\_\_$ litre.
(Take $1 \mathrm{~atm}=10^5 \mathrm{~Pa}$ ).
Solution:

Given,
Initial pressure of liquid $\left(P_i\right)=1 \mathrm{~atm}$
Final pressure of liquid $\left(P_f\right)=5 \mathrm{~atm}$
Change in pressure $(\Delta P)=P_f-P_i=4 \mathrm{~atm}$

(Take $1 \mathrm{~atm}=10^5 \mathrm{~Pa}$ ).
Solution:
Given,
Initial pressure of liquid $\left(P_i\right)=1 \mathrm{~atm}$
Final pressure of liquid $\left(P_f\right)=5 \mathrm{~atm}$
Change in pressure $(\Delta P)=P_f-P_i=4 \mathrm{~atm}$

$
=4 \times 10^5 \mathrm{~Pa}
$

Change in volume $(\Delta V)=-0.8 \mathrm{~cm}^3$

Bulk modulus $(B)=2 \times 10^9 \mathrm{~Pa}$
Now,

$
\begin{gathered}
B=-\frac{\Delta P}{(\Delta V / V)} \Rightarrow V=-\frac{B(\Delta V)}{\Delta P} \\
\Rightarrow V=-\frac{2 \times 10^9 \times\left(-0.8 \times 10^{-6}\right)}{4 \times 10^5}=4 \times 10^{-3} \mathrm{~m}^3=4 \text { litre }
\end{gathered}
$

Hence, the answer is 4 .

4. Magnetic Effects of Current & Magnetism

Q: The percentage increase in magnetic field B when the space within a current-carrying solenoid is filled with magnesium (magnetic susceptibility

$\left.\chi_{\mathrm{Mg}}=1.2 \times 10^{-5}\right) \mathrm{is}:$
1. $65 \times 10^{-3} \%$
2. $56 \times 10^{-5} \%$
3. $56 \times 10^{-4} \%$
4. $53 \times 10^{-5} \%$

Solution:

$\begin{gathered}\% \text { change in } B=\frac{B_{\text {new }}-B_{\text {old }}}{B_{\text {old }}} \times 100 \% \\ =\frac{\mu n i-\mu_0 n i}{\mu_0 n i} \times 100 \%=\frac{\mu-\mu_0}{\mu_0} \times 100 \%=\frac{\mu_0 \mu_r-\mu_0}{\mu_0} \times 100 \% \\ =\left(\mu_r-1\right) \times 100 \%=\chi_m \times 100 \%=1.2 \times 10^{-3} \%\end{gathered}$

Hence, the answer is option (1).

5. Rotational Motion

Q: A solid sphere of mass 2 kg and radius 0.2 m rolls without slipping with a linear speed of 5 m/s. Find its total kinetic energy.

Solution:

$\begin{gathered}K_{\text {total }}=K_{\text {trans }}+K_{\mathrm{rot}} \\ K_{\text {trans }}=\frac{1}{2} m v^2 \\ K_{\mathrm{rot}}=\frac{1}{2} I \omega^2 \\ I=\frac{2}{5} m r^2 \\ K_{\text {trans }}=\frac{1}{2} \times 2 \times 5^2 \\ K_{\text {trans }}=25 \mathrm{~J} \\ K_{\mathrm{rot}}=\frac{1}{2}\left(\frac{2}{5} m r^2\right)\left(\frac{v}{r}\right)^2\end{gathered}$

$\begin{gathered}K_{\text {rot }}=\frac{1}{2}\left(\frac{2}{5} m r^2\right)\left(\frac{v^2}{r^2}\right) \\ K_{\text {rot }}=\frac{1}{5} m v^2 \\ K_{\text {rot }}=\frac{1}{5} \times 2 \times 5^2 \\ K_{\text {rot }}=\frac{1}{5} \times 50 \\ K_{\text {rot }}=10 \mathrm{~J} \\ K_{\text {total }}=K_{\text {trans }}+K_{\text {rot }} \\ K_{\text {total }}=25 \mathrm{~J}+10 \mathrm{~J} \\ K_{\text {total }}=35 \mathrm{~J}\end{gathered}$

JEE Main Maths Chapter-Wise PYQ

Maths is a tricky subject. It requires a lot of practice. Your main aim in maths should be to increase speed and accuracy. Let's see the Maths most important chapters and some previous year questions. JEE Main Maths chapter-wise PYQ PDF, along with chapter-wise distribution, is given as follows:

JEE Mains Maths previous Year questions:

Let's see some previous years' questions from JEE Mains Maths.

1. Co-ordinate Geometry

Q: Let A(4,−2),B(1,1) and C(9,−3) be the vertices of a triangle ABC . Then the maximum area of the parallelogram AFDE, formed with vertices D,E and F on the sides BC,CA and AB of the triangle ABC respectively, is________

Solution:

Given:

$\begin{aligned} & \mathrm{A}(4,-2), \mathrm{B}(1,1), \mathrm{C}(9,-3) \\ & \qquad \begin{aligned} & \triangle A B C=\frac{1}{2}\left|x_1\left(y_2-y_3\right)+x_2\left(y_3-y_1\right)+x_3\left(y_1-y_2\right)\right| \\ &= \frac{1}{2}|4(1+3)+1(-3+2)+9(-2-1)| \\ &= \frac{1}{2}|4 \times 4+1 \times(-1)+9 \times(-3)| \\ &= \frac{1}{2}|16-1-27| \\ &= \frac{1}{2}|-12| \\ &=6\end{aligned}\end{aligned}$

Use the property: Area of parallelogram formed on the same base and height =2×Area of triangle

So, the maximum area of the parallelogram AFDE inscribed with vertices on sides BC, CA, AB

= 2×Area of △ABC = 2×6 = 12

Hence, the answer is 12 sq. units.

2. Integral Calculus

Q: If $\int\left(\frac{1}{x}+\frac{1}{x^3}\right)\left(2 x^3-3 x^2+x^{-2}-6\right) d x=-\frac{\alpha^3}{(\alpha+1)}\left(3 x^\beta+x^\gamma\right)^{\alpha+1} \frac{1}{\alpha}+C, x>0,(\alpha, \beta, \gamma \in Z)$, where C is the constant of integration, then $\alpha+\beta+\gamma$ is equal to $\_\_\_\_$。

Solution:

$
I=\int\left(\frac{1}{x}+\frac{1}{x^3}\right)\left(3 x^{24}+\frac{1}{x^{26}}\right)^{\frac{1}{23}} d x=\int\left(\frac{1}{x^2}+\frac{1}{x^4}\right)\left(3 x+\frac{1}{x^3}\right)^{\frac{1}{23}} d x
$

Put $3 x+\frac{1}{x^3}=t \Rightarrow\left(-3 x^2-3 x^4\right) d x=d t$

$
\begin{gathered}
\Rightarrow I=-\frac{1}{3} \int t^{\frac{1}{23}} d t=-\frac{1}{3} \cdot \frac{t^{\frac{1}{23}}+1}{\frac{1}{23}+1}+C \\
=-\frac{1}{3} \times \frac{23}{24}\left(3 x-1+x^{-3}\right)^{\frac{24}{23}}+C \\
\Rightarrow \alpha=23, \beta=-1, \gamma=-3 \\
\alpha+\beta+\gamma=19
\end{gathered}
$

Hence, the answer is (19).

3. Limit, Continuity & Differentiability

Q: If $\lim _{x \rightarrow 0} \frac{\cos (2 x)+a \cos (4 x)-b x}{4}$ is finite, then $(a+b)$ is equal to:

1) 12

2) 0

3) 34

4) -1

Solution:

Given that the limit

$\lim _{x \rightarrow 0} \frac{\cos (2 x)+a \cos (4 x)-b x}{4}$ is finite,
we need to find $a+b$.

Using the Maclaurin series expansions near $\mathrm{x}=0$ :

$
\begin{aligned}
& \cos (2 x)=1-\frac{(2 x)^2}{2}+\frac{(2 x)^4}{24}+\cdots=1-2 x^2+\frac{4 x^4}{3}+\cdots \\
& \cos (4 x)=1-\frac{(4 x)^2}{2}+\frac{(4 x)^4}{24}+\cdots=1-8 x^2+\frac{32 x^4}{3}+\cdots
\end{aligned}
$

Substitute these into the numerator:

$
\cos (2 x)+a \cos (4 x)-b=\left(1-2 x^2+\frac{4 x^4}{3}\right)+a\left(1-8 x^2+\frac{32 x^4}{3}\right)-b+\cdots
$

Simplify the expression:

$
(1+a-b)+(-2-8 a) x^2+\left(\frac{4}{3}+\frac{32 a}{3}\right) x^4+\cdots
$

For the limit to be finite, the coefficients of the $x^0$ and $x^2$ terms must be zero, otherwise the numerator will not vanish at order $x^4$.

Set the constant term to zero:

$
1+a-b=0 \Rightarrow b=1+a
$

Set the coefficient of $x^2$ to zero:

$
-2-8 a=0 \Rightarrow a=-\frac{1}{4}
$

Use $a=-\frac{1}{4}$ to find $b$ :

$
b=1-\frac{1}{4}=\frac{3}{4}
$

Therefore, $a+b=-\frac{1}{4}+\frac{3}{4}=\frac{1}{2}$

Hence, the correct answer is option (1).

4. Sets, Relations and Functions

Q:The number of real roots of the equation $x|x-2|+3|x-3|+1=0$ is:

1) 4

2) 2

3) 1

4) 3

Solution: $x|x-2|+3|x-3|+1=0$
Case I: $x<2$

$
\begin{gathered}
-x(x-2)-3(x-3)+1=0 \\
-x^2+2 x-3 x+9+1=0 \\
x^2+x-10=0 \\
x=-1-\frac{\sqrt{41}}{2} \text { or }-1+\frac{\sqrt{41}}{2} \text { (rejected) }
\end{gathered}
$

1 solution

Case II: $2 \leq x<3$

$
\begin{gathered}
x(x-2)-3(x-3)+1=0 \\
x^2-5 x+8=0
\end{gathered}
$

No solution

Case III: $x \geq 3$

$
\begin{gathered}
x(x-2)+3(x-3)+1=0 \\
x^2+x-8=0 \\
x=-1 \pm \frac{\sqrt{33}}{2}(\text { no solution })
\end{gathered}
$

$\therefore x=-1-\frac{\sqrt{41}}{2}$ is the only solution

Hence, the correct answer is option (3).

5. Complex Numbers and Quadratic Equations

Q : If the set of all $a \in R \backslash\{1\}$, for which the roots of the equation $(1-a) x^2+2(a-3) x+9=0$ are positive is $(-\infty,-\alpha] \cup[\beta, \gamma)$, then $2 \alpha+\beta+\gamma$ is equal to $\_\_\_\_$

Solution:

Given the equation: $(1-a) x^2+2(a-3) x+9=0$

Let $\mathrm{f}(\mathrm{x})=f(x)=(1-a) x^2+2(a-3) x+9$

To ensure both roots are positive:

$
\begin{gathered}
D \geq 0 \\
D=[2(a-3)]^2-4(1-a)(9)=4(a-3)^2-36(1-a)
\end{gathered}
$

(i) Discriminant

$
\begin{gathered}
=4\left[a^2-6 a+9+9 a-9\right]=4\left(a^2+3 a\right) \geq 0 \\
\Rightarrow a(a+3) \geq 0 \Rightarrow a \in(-\infty,-3] \cup[0, \infty)
\end{gathered}
$

(ii) Leading coefficient (1-a) $>0 \Rightarrow a<1$
(iii) $f(0)=9>0$, always true

(iv) Vertex should lie to the left of $y$-axis:

$
-\frac{b}{a}=-\frac{2(a-3)}{1-a}>0 \Rightarrow \frac{3-a}{1-a}>0 \Rightarrow a \in(-\infty, 1)
$

Final intersection of conditions $a \in(-\infty,-3] \cup[0,1)$
This is of the form $(-\infty,-\alpha] \cup[\beta, \gamma)$

$
\begin{gathered}
\Rightarrow \alpha=3, \beta=0, \gamma=1 \\
\Rightarrow 2 \alpha+\beta+\gamma=2(3)+0+1=7
\end{gathered}
$

Hence, the answer is 7.

How to Use PYQs for Scoring 150+ in JEE Main

It is by far the best source to improve your JEE Main score using Previous Years' Questions (PYQs). Once you figure out what the exam demands, scoring 150+ becomes much easier, and that is precisely what PYQs help you decode. It tells you the patterns of questions, concepts most repeated, and the perfect precision and quickness required for scoring well.

The smart strategy isn’t just solving PYQs but learning from them:

Learn Important Topics: These are usually the high-weightage chapters which the previous year's questions suggest, Kinematics, Chemical Bonding, Current Electricity, and Coordinate Geometry.

Trends in Questions: Find out how questions change every year. Sometimes the same concept is asked in a twisted way.

Understanding the JEE Pattern: You will actually feel how difficult it is, how questions are framed, and then some tricky distractors will be there in MCQs.

Speed & Accuracy: Time-bound practice through original papers helps you in speeding up their solutions for a gain with no loss of marks.

Constructing Exam Temperament: Solving previous years' papers gives due practice, decreases anxiety, boosts confidence, and improves decision-making in the exam.

Going through every paper thoroughly marking the errors, going through and revising less strong concepts, and practicing like problems should in itself boost your score to move beyond 150 with PYQs-difficult as starting late or going over information again could well be-but without having to study.
