Q. 2

Inside a uniform spherical shell
A. The gravitational potential is zero

B. The gravitational field is zero

C. The gravitational potential is same everywhere

D. The gravitational field is same everywhere.

Answer :

Inside a shell, the gravitational field is zero, while gravitational potential exists and is constant. So, (a) is wrong and (b) is correct. As the potential is constant, (c) is true. The value of gravitational field inside a sphere is zero everywhere. Hence (d) is true.
