Two particles of masses m and M are initially at rest at an infinite distance apart. They move towards each other and gain speeds due to gravitational attraction. Find their speeds when the separation between the masses becomes equal to d.

If g is the acceleration due to gravity on the earth's surface is the gain in the potential energy of an object of mass m raised from the surface of the earth to a height equal to the radius R of the earth
