Problem
Eight particles, each of mass m, are situated at the corners of a cube of side a. Find the gravitational force exerted on any one of the particles by the other seven.
Deduce the total gravitational force exerted on the four particles lying on one face of the cube by the four particles lying on the opposite face.
