The magnitude of the gravitational force between a particle of mass m 1 and one of mass m 2 is given by F ( x ) = G m 1 m 2 x 2 , where G is a constant and x is the distance between the particles. (a) What is the corresponding potential energy function U ( x )? Assume that U ( x ) → 0 as x → ∞ and that x is positive. (b) How much work is required to increase the separation of the particles from x = x 1 to x = x 1 + d ?
