    Changes in JEE Main Question Paper

    There is a significant difference between JEE Main question papers as compared to previous years, with respect to exam syllabus, exam pattern, number of questions etc for Paper 1 (i.e. for B.E./ B. Tech). Let's discuss them one by one

    • JEE Main Syllabus:- Major chapters from all three subjects have been deleted from the current JEE Main Syllabus with respect to previous year JEE Main Syllabus.

    Here are the details about the syllabus that is removed.

    Subject

    Chapter Name

    Physics

    Communication System

    Physical Chemistry

    States of Matter

    Surface Chemistry

    Inorganic Chemistry

    General Principles and Processes of Isolation of Metals

    Hydrogen

    S-Block Elements (Alkali and Alkaline Earth Metals)

    Environmental Chemistry

    Organic Chemistry

    Polymers

    Chemistry in Everyday Life

    Mathematics

    Mathematical Inductions

    Mathematical Reasoning

    The above-mentioned chapters are completely removed from the JEE Main Syllabus along with major topics from other remaining chapters also reduced.

    For detailed analysis have a look at JEE Main Syllabus

    • Exam patterns:-

    1. Total marks- The total marks are the same. I.e Students can achieve a maximum of 300 marks in the main exam.

    2. No of Questions- Let's have a look at Subject wise distribution of the total number of questions for the JEE Main exams.

    Subject

    No of Questions

    No of Questions

    Mathematics

    (20 MCQs+ 5 NAT)

    (20 MCQs+ 5 NAT)

    Physics

    (20 MCQs+ 5 NAT)

    (20 MCQs+ 5 NAT)

    Chemistry

    (20 MCQs+ 5 NAT)

    (20 MCQs+ 5 NAT)

    Here MCQs mean Multiple-Choice Questions and NTA means questions whose answers are to be filled in as a numerical value. So to summarize in JEE Main for section B in each subject 5 NTA-type questions are there, but candidates have to attempt all 5 of them.

    Few Solved Questions from JEE Main 2020 Paper

    1. (Subject - Physics, Chapter - Optics, Shift - 06 Sep - Evening Shift)

    Question:- A double convex lens has power P and the same radii of curvature R of both surfaces. The radius of curvature of the surface of a planoconvex lens made of the same material with power 1.5 P is :

    1. 2R

    2. \frac{R}{2}

    3. \frac{3R}{2}

    4. \frac{R}{3}

    Answer- 4) \frac{R}{3}

    Solution:-

    1720600855410

    \mathrm{R}_{1}=\mathrm{R}_{2}=\mathrm{R} \\ Power= P \\ \text{Refractive index is assume} (\mu_{l})

    \mathrm{P}=\frac{1}{\mathrm{f}}=\left(\mu_{l}-1\right)\left(\frac{2}{\mathrm{R}}\right)

    1720600856679

    \begin{aligned} &\mathrm{P}^{\prime}=\frac{1}{\mathrm{f}^{\prime}}=\left(\mu_{\ell}-1\right)\left(\frac{1}{\mathrm{R}^{\prime}}\right)\\ &P^{\prime}=\frac{3}{2} P \end{aligned}

    \begin{array}{l} \left(\mu_{\ell}-1\right)\left(\frac{1}{\mathrm{R}^{\prime}}\right)= \frac{3}{2}\left(\mu_{\ell}-1\right)\left(\frac{2}{\mathrm{R}}\right) \\ \\ \therefore \quad \mathrm{R}^{\prime}=\frac{\mathrm{R}}{3} \end{array}


    Hence, The correct option is (4)


    2. (Subject - Maths, Chapter - Integral Calculus, Shift - 03 Sep - Evening Shift )

    Question:- If \int \sin ^{-1}\left ( \sqrt{\frac{x}{1+x}} \right )dx=A(x)\tan ^{-1}(\sqrt{x})+B(x)+C, where C is a constant of integration, then the ordered pair (A(x),\; B(x)) can be?

    1. (x+1,\; -\sqrt{x})

    2. (x+1,\; \sqrt{x})

    3. (x-1,\; -\sqrt{x})

    4. (x-1,\; \sqrt{x})

    Answer- 1) (x+1,\; -\sqrt{x})

    Solution:-

    Given,

    \int \sin ^{-1}\left ( \sqrt{\frac{x}{1+x}} \right )dx=A(x)\tan ^{-1}(\sqrt{x})+B(x)+C,

    \begin{array}{l} \text { Put } x=\tan ^{2} \theta \Rightarrow d x=2 \tan \theta \sec ^{2} \theta d \theta \\ \int \theta \cdot\left(2 \tan \theta \cdot \sec ^{2} \theta\right) d \theta \end{array}

    Now do the integration by parts

    \\\mathrm{\theta\rightarrow 1st\;function}\\\mathrm{2\tan\theta\sec^2\theta\rightarrow 2nd\;function}

    \begin{array}{l} =\theta \cdot \tan ^{2} \theta-\int \tan ^{2} \theta \mathrm{d} \theta \\ =\theta \cdot \tan ^{2} \theta-\int\left(\sec ^{2} \theta-1\right) \mathrm{d} \theta \\ =\theta\left(1+\tan ^{2} \theta\right)-\tan \theta+\mathrm{C} \\ =\tan ^{-1}(\sqrt{\mathrm{x}})(1+\mathrm{x})-\sqrt{\mathrm{x}}+\mathrm{C} \end{array}

    A(x)=1+x,\;\;B(x)=-\sqrt x

    Hence, the answer is the option 1.


    3. (Subject - Chemistry, Chapter - Hydrocarbons, Shift - 08 Jan - Morning Shift)

    Question:- The major products A and B in the following reactions are:

    1720600856029


    1. 1720600856074

    2. 1720600854949

    3. 1720600855903

    4. 1720600855239


    Answer- 1) 1720600856126

    Solution:-

    The given reaction occurs as :

    \mathrm{R-O-O-R\xrightarrow[]{\Delta}2R\dot{O}}

    1720600856280

    Therefore, Option(1) is correct.
