Two bodies of masses m1​ and m2​ are initially at rest at infinite distance apart. They are then allowed to move towards each other under mutual gravitational attraction. Their relative velocity of approach at a separation distance r between them is

The escape velocity from earth is ves. A body is projected with velocity 2 ves with what constant velocity will it move in the inter planetary space
