There is a shell of mass M and density of shell is uniform. The work done to take a point mass from point A to B is `(AB = r)`

A

`(GmM)/(r )`

B

`(GmM)/(R)`

C

`-(GmM)/(r)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D

The gravitational field at A and B are zero. So no work required to make charge between the points A and B.
