`16 kg` and `9kg` are separated by `25m`. The velocity with which a body should be projected from the mid point of the line joining the two masses so that it just escape is

If d is the distance between the centre of the earth of mass M_(1) and the moon of mass M_(2) , then the velocity with which a body should be projected from the mid point of the line joining the earth and the moon, so that it just escape is

The radii of a planet and its satellite are 2r and r and their densities are rho and 2rho respectively. Their centres are separated by a distance d. The minimum speed with which a body should be projected from the mid point of the line joining their centres so that the body escapes to infinity is (G-universal gravitational constant)

Two bodies of masses 10 kg and 100 kg are seperated by a distance of 2 m. The gravitational potential at the mid-point of the line joining the two bodies is:
