A mass `m` is placed inside a hollow sphere of mass M as shown in figure. The gravitaional force on mass `m` is

A

`(GMm)/(R^(2))`

B

`(GMm)/(r^(2))`

C

`(GMm)/((R-r)^(2))`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
Inside a shell, field strength is zero. Therefore, force on a particle is zero.
