A current is passing through a cylindrical conductor with a hole (or cavity) inside it. Show that the magnetic field inside the hole is uniform and find its magnitude and direction.

The magnetic field inside finite solenoid is uniform

A sphere of radius R has its centre at the origin. It has a uniform mass density rho_(0) except that there is a spherical hole of radius r=R//2 whose centre is at x=R//2 as in fig (a) find gravitational field at points on the axis for xgtR (ii) Show that the gravitational field inside the hole is uniform, find its magnitude and direction.
