Question

At all points inside a uniform spherical shell -

• A. gravitational intensity and gravitational potential both are zero
• B. gravitational intensity and gravitational potential both are non- zero
• C. gravitational intensity is non- zero and gravitational potential both are zero
• D. gravitational intensity is zero and gravitational potential both are non-zero

Answer 1

The correct option is A gravitational intensity and gravitational potential both are zero

Gravity Force Inside a Spherical Shell. The net gravitational force on a point mass inside a spherical shell of mass is identically zero! Physically, this is a very important result because any spherically symmetric mass distribution outside the position of the test mass m can be build up as a series of such shells
