With what minmum speed should `m` be projected from point `C` in presence of two fixed masses `M` each at `A` and `B` as shows in the figure such that mass `m` should escape the gravitational of `A` and `B` ?

With what speed v_(0) should a body be projected as shown in the figure, with respect to a planet of mass M so that it would just be able to graze the planet and escape ? The radius of the planet is R . (Assume that the planet is fixed ).

A chain of mass 'm' is attached at two points A and B of two fixed walls as shown in the figure. The tension in the chain at A is

Find the potential V at P in the gravitational field of fixed point mass M .

Find the potential V at P in the gravitational field of fixed point mass M .

Two point masses m and 2m are kept at points A and B as shown. E represents magnitude of gravitational field strength and V the gravitational potential. As we move from A to B
