The magnitude of the gravitational field at distances r 1 & r 2 from the centre of a uniform sphere of radius R & mass M are F 1 & F 2 respectively then -
A
= 
if r 1 < R & r 2 < R
B
= 
if r 1 > R & r 2 > R
C
= 
if r 1 > R & r 2 > R
D
= 
if r 1 < R & r 2 < R
Text Solution
Verified by ExpertsThe correct answer is:
A
We know for uniform sphere when r < R
F = 
& when r > R
F = 
so when r 1 < R & r 2 < R
= 
& when r 1 > R & r 2 > R
=
