Fig. 3.1 displays a single isolated point mass with mass $M$. Point P is located a distance $x$ from this mass. In Fig. 3.3, two identical isolated uniform spheres X and Y, each with radius $R$, have centres separated by a distance $L$ as shown. Point P lies on the line joining the centres of X and Y, and its variable displacement from the centre of sphere X is $x$. The gravitational field strength at the surface of each sphere is $g_0$.
