JEE Main 2021 — Gravitation Question with Solution
From: JEE Main 2021 (Online) 25th February Morning Shift
Question
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The escape velocities of planet A and B are same. But A and B are of unequal mass.
Reason R : The product of their mass and radius must be same. M1R1 = M2R2
In the light of the above statements, choose the most appropriate answer from the options given below :

Correct answer
CA is correct but R is not correct
Step-by-step explanation
= escape velocity
so for same
A is true but R is false
so for same
A is true but R is false
