The figure below shows a spherical hollow inside a lead sphere of radius R $=4\mathrm{.}00$ cm$.$ The surface of the hollow passes through the center of the sphere and "touches" the right side of the sphere. The mass of the sphere before hollowing was M $=3\mathrm{.}45$ kg$.$ With what gravitational force does the hollowed$-$out lead sphere attract a small sphere of mass m $=0\mathrm{.}389$ kg that lies at a distance d $=9\mathrm{.}00$ cm from the center of the lead sphere, on the straight line connecting the centers of the spheres and of the hollow?
