- The figure shows a spherical hollow inside a lead sphere of radius R; the surface of the hollow passes through the centre of the sphere and touches the right side of the sphere. The mass of the sphere before hollowing was M. With what gravitational force does the hollowed-out lead sphere attract a small sphere of mass m that lies at a distance d from the centre of the lead sphere, on the straight line connecting the centres of the spheres and of the hollow?
