PROBLEM:1.206

   Find the potential energy of the gravitational interaction
(a)   of two mass points of masses m1 and m2 located at a distance r from each other;
(b)   of a mass point of mass m and a thin uniform rod of mass M and length L, if they are located along a straight line at a distance a from each other; also find the force of their interaction.
