Hence, the answer is the option (1).

De-broglie wavelength of an electron

Q.1 A proton of mass mp has the same energy as that of a photon of wavelength λ. If the proton is moving at a non-relativistic speed, then the ratio of its de Broglie wavelength to the wavelength of the photon is:

1) 1c2Emp

2) 1cEmp

3) 1cE2mp

4) 12cEmp

Correct Answer: 1cE2mp

Energy of photon:

Ephoton=hcλ=E

Energy of proton:

Eproton=12mpv2=E


De-Broglie wavelength of proton:

λp=hp=h2mpE

Ratio:

λpλphoton

= h2mpEhcE

= 1cE2mp

Hence, the answer is Option (3).


---

Amplitude Modulation

Q.1Given below are two statements:

Statement I: For transmitting a signal, the size of the antenna should be comparable to the wavelength of the signal
(at least l=λ4)

Statement II: In amplitude modulation, the amplitude of the carrier wave remains constant (unchanged).

Options:

1. Statement I is correct but Statement II is incorrect

2. Both Statement I and Statement II are correct

3. Statement I is incorrect but Statement II is correct

4. Both Statement I and Statement II are incorrect

Correct Answer: Statement I is correct but Statement II is incorrect

Solution:

- Statement I is correct.

- In amplitude modulation, amplitude of the carrier wave is varied, not constant.

Hence, the answer is Option (1).

Projectile Motion

Q.1 A ball having kinetic energy KE is projected at an angle of 60∘ with the horizontal. What will be the kinetic energy at the highest point of its flight?

1) KE8

2) KE4

3) KE16

4) KE2

Correct Answer: KE4

Solution:

Initial kinetic energy:

KE=12mu2

At the highest point:

v = u cos60=u2

KEf=12m(u2)2=KE4

Nature of Electromagnetic Waves

Q.1 The electric field of an electromagnetic wave in free space is:

E=57cos[7.5×106t5×103(3x+4y)](4i^3j^) N/C

The associated magnetic field in Tesla is:

1.B=573×108cos[](5k^)

2.B=573×108cos[](k^)

3.B=573×108cos[](5k^)

4.B=573×108cos[](k^)

Correct Answer: Option (3)

Solution:

Magnitude:

|B0|=|E0|c,E0=57×5

Direction:

B^=c^×E^

= (3i^+4j^5)×(4i^3j^5)

= k^

So,

B=573×108cos[](5k^)

Hence, the answer is Option (3).

---

Hooke’s Law

Q.1 Two wires A and B are made of the same material. Their length ratio is LA:LB=1:3, and their diameter ratio is dA:dB=2:1. If both are stretched by the same force, find the ratio of elongations ΔLA:ΔLB.

- Option 1: 1 : 6

- Option 2: 1 : 12

- Option 3: 3 : 4

- Option 4: 1 : 3

Correct Answer: 1 : 12

Solution:

ΔLAΔLB

= (LALB)(dBdA)2

= 13(12)2

= 112

Hence, the answer is Option (2).

---

Kinetic Energy

Q.1 A car accelerates from rest to u m/s, spending energy E. The energy required to further accelerate it from u to 2u m/s is nE. Find n.

Correct Answer: 3

Solution:

E1=12mu2=E

E2=12m(2u)212mu2=32mu2=3E

So, n = 3.

---

Parallel Grouping of Resistance

Q.1 10 resistors each of 10 Ω are connected in such a way as to obtain maximum and minimum resistance. Find the ratio RmaxRmin.

Correct Answer: 100

Solution:

Rmax=10×10=100 Ω(series)

Rmin=1010=1 Ω(parallel)

RmaxRmin=1001=100

---

Adiabatic Process

Q.1 A gas expands adiabatically from 8 L to 27 L. If P2P1=1681, then find CpCv.

- Option 1: 12

- Option 2: 43

- Option 3: 32

- Option 4: 3

Correct Answer: 43

Solution:

For adiabatic process:

P1V1γ=P2V2γ

(827)γ=1681

(23)3γ=(23)4

3γ=4γ=43

Hence, the answer is Option (2).

---

Newton’s Second and Third Law of Motion

Q.1 A force (10i^+5j^) N acts on a mass of 100 g. The position of the object at t=2 s, starting from rest, is (ai^+bj^) m. Find the ratio ab.

here

Correct Answer: 2

Solution:

F=(10i^+5j^),m=0.1 kg

a = Fm=(100i^+50j^)

Displacement:

s=ut+12at2

=12(100i^+50j^)(4)

= 200i^+100j^

So,

a=200,b=100,ab=2

Frequently Asked Questions (FAQs)

Q: How should I prioritize my preparation for the top 10 Physics chapters?
A:

Start with chapters that have both high conceptual weightage and numerical applications, such as Optics, Electrostatics, and Current Electricity. Once strong in these, move to moderate-weightage topics to maximize overall coverage.

Q: Can NCERT textbooks alone cover the top 10 important Physics chapters?
A:

NCERT is an excellent foundation, but for problem-solving and numerical practice, reference books and question banks are also necessary, especially for competitive exams like JEE and MHT CET.

Q: Which Physics chapter carries the highest weightage in competitive exams?
A:

Optics, Electrostatics, Current Electricity, and Properties of Solids and Liquids are usually among the highest-weightage chapters based on past trends.

Q: Do I need to study only the top 10 Physics chapters to score well?
A:

No, while focusing on the top 10 chapters gives an edge in scoring, it is recommended to cover the entire syllabus since exams often include a mix of high-weightage and moderate-weightage topics.

Q: How are the top 10 most important Physics chapters determined?
A:

The list of important chapters is based on the frequency of questions asked in previous years’ exams, the weightage of topics in the official syllabus, and their overall significance in scoring well.

Questions related to JEE Main

On Question asked by student community

Have a question related to JEE Main ?

As of now, the official chapter-wise weightage for JEE Main 2026 has not been released by the National Testing Agency (NTA). However, based on previous years' data, we can anticipate that the weightage distribution across Physics, Chemistry, and Mathematics will remain relatively consistent. For instance, in JEE Main 2025, key topics such as Modern Physics, Thermodynamics, and Organic Chemistry held significant weightage. It's advisable to focus on these high-weightage chapters while also covering the entire syllabus to ensure comprehensive preparation. Once the official weightage for JEE Main 2026 is published, it will provide more precise guidance for targeted study.
