A point mass m is placed inside a spherical shell of radius R and mass M at a distance `R/2` form the centre of the shell. The gravitational force exerted by the shell on the point mass is

A

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

B

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

C

zero

D

`(4Mm)/(R^(2))`

Text Solution

Verified by Experts

The correct Answer is:
C
( c) If a point mass is placed inside a uniform spherical shell, the gravitational force on the point mass is zero. Hence, the gravitational force exerted by the shell on the point mass is zero.
