A particle of mass `M` is at a distance a from surface of a thin spherical shell of equal mass and having radius `a`.

A

Gravitational field and potential both are zero at centre of the shell.

B

Gravitational field is zero not only inside the shell but at a point outside the shell also.

C

Inside the shell, gravitational field alone is zero.

D

Neither gravitational field nor gravitational potential is zero inside the shell.

Text Solution

Verified by Experts

The correct Answer is:
D

Both field and the potential inside the shell in non zero.
