Problem
A thin uniform spherical shell has radius R and total mass M.
(a) Prove that the gravitational field intensity at an internal point situated at a distance x(<R) from the centre of the shell is zero.
(b) Obtain an expression for the gravitational field intensity at an external point situated at a distance r(>R) from the centre, and comment on its dependence on r.
