Two point masses m and M are held at rest at a large distance from each other. When released, they begin moving under their mutual gravitational pull.Find their relative acceleration (a) when separation between them becomes x.Integrate the expression of a obtained above to calculate the relative velocity of the two masses when their paration is x. Write the velocity of centre of mass of the system when separation between them is x.
