Question

Inside a hollow isolated spherical shell

• A. everywhere gravitational potential is zero.
• B. everywhere gravitational field is zero.
• C. everywhere gravitational potential is same.
• D. everywhere gravitational field is same.

Answer 1

Answer: (B), (C), (D)

The correct options are
B everywhere gravitational field is zero.
C everywhere gravitational potential is same.
D everywhere gravitational field is same.

The gravitational field inside a spherical shell is zero throughout.
Because of this zero field there is no change in the potential (potential changes only when the field is non zero).
Thus B,C,D are correct.
