We all know that the gravitational field inside a thin spherical shell is zero. There are different methods to prove this. I came across one such odd yet amazing method . I would like everyone to try proving it by this method .I will put my proof in a couple of days.

Zero force inside a sphere.

Show that the gravitational force inside a spherical shell is zero by showing

that the pieces of mass at the ends of the thin cones in the figure give

canceling forces at point P (any point inside the sphere).

same can you prove the same thing for an ellipsoid?Log in to reply

Ellipsoid will be having the same proof. There'll be a change in diagram. Rest all will be the same thing.Log in to reply

I'll try that also. Thanks for enlightening.Log in to reply

The tougher task is doing the same thing for an ellipsoid. I am trying to prove that! Might take a couple of days. – Ayush Shridhar · 1 year, 4 months ago
