Question

two bodies of masses m1 and m2 are initially at rest placed at
infinite dist apart they are then allowed to move towards each
other under at mutual gravitational attaration show that their
relative velocity of approach at separation r between them is
v=2G^1+2 (m1+m2)+r

Dear Student,

two bodies of masses m1 and m2 are initially at rest placed at infinite dist. apart they are then allowed to move towards each other under at mutual gravitational attaration show that their relative velocity of approach at separation r between them is v=2G^1+2 (m1+m2)+r
