By what percent the energy of the satellite has to be increased to shift it from an orbit of radius `r` to `(3r)/2`.

A satellite of mass 1000 kg is rotating around the earth in a circular orbit of radius 3R . What extra energy should be given to this satellite if it is to be lifted into an orbit of radius 4R ?

If W is the weight of a satellite on the surface of the earth, then the energy required to lauch that satellite from the surface of earth into a circular orbit of radius 3R is (here R is the radius of the earth)
