If a body of mass 1 kg falls on the Earth from infinity, it attains velocity ( v ) and kinetic energy ( k ) on reaching the surface of Earth. The values of v and k respectively are __________. (Take radius of Earth to be 6400 km and g = 9.8 m/s 2 )

11.2 km/s; $6.27 \times 10^7$ J

11.2 km/s; $12.54 \times 10^7$ J

8.8 km/s; $12.54 \times 10^7$ J

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The radius vector from the Sun to a planet sweeps out equal areas in equal intervals of time and thus the areal velocity of the planet is constant. Reason (R): For a central force field the angular momentum is a constant. In the light of the above statements, choose the most appropriate answer from the options given below:

Both (A) and (R) are correct and (R) is the correct explanation of (A)

(A) is not correct but (R) is correct

Both (A) and (R) are correct but (R) is not the correct explanation of (A)

(A) is correct but (R) is not correct

Correct formula for height of a satellite from Earth's surface is :

$$\left(\frac{T^2 R^2 g}{4 \pi^2}\right)^{1 / 3}-R$$

$$\left(\frac{T^2 R^2 g}{4 \pi}\right)^{1 / 2}-R$$

$$\left(\frac{T^2 R^2 g}{4 \pi^2}\right)^{-1 / 3}+R$$

$$\left(\frac{T^2 R^2}{4 \pi^2 g}\right)^{1 / 3}-R$$

How many JEE Main questions come from Gravitation?

Gravitation has contributed 187 questions to Joint Entrance Examination (Main) papers between 2016 and 2026 — an average of about 17 questions a year. That count is measured from EByAi’s bank of 55,289 JEE Main questions, not estimated from a syllabus. Every one of the 187 questions carries a written, step-by-step solution, and each is tagged to Gravitation within Physics, so you can drill this chapter across every year at once instead of hunting through paper PDFs. Practising a chapter’s full PYQ history is the fastest way to learn the patterns examiners reuse.

2. (B) $2.5%$
3. (C) $4.5%$
4. (D) $9%$
Show answerAnswer
$Answer: (C) 4.5%$
Question 4 · JEE Main 2025
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The radius vector from the Sun to a planet sweeps out equal areas in equal intervals of time and thus the areal velocity of the planet is constant. Reason (R): For a central force field the angular momentum is a constant. In the light of the above statements, choose the most appropriate answer from the options given below:
1. (A) $(A) is not correct but (R) is correct$
2. (B) $Both (A) and (R) are correct but (R) is not the correct explanation of (A)$
3. (C) $Both (A) and (R) are correct and (R) is the correct explanation of (A)$
