Question

What is the gravitational field at a point inside a spherical shell?​

Answer 1

Answer:

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.
