Consider a hollow sphere of mass M and radius R resting on a smooth surface. A smaller sphere of mass m and radius r is Initialy held at position P within the bigger sphere. If the small sphere is now released, it rolls down through the inner surface of hollow sphere and finally stops at its bottom point Q. Then:
