Two Earth satellites, A and B, each of mass m, are to be launched into circular orbits

Question:

Two Earth satellites, A and B, each of mass m, are to be launched into circular orbits about Earth's center. Satellite A is to orbit at an altitude of 6370 km. Satellite B is to orbit at an altitude of 19110 km. The radius of Earth RE is 6370 km.

(a) What is the ratio of the potential energy of satellite B to that of satellite A, in orbit?

(b) What is the ratio of the kinetic energy of satellite B to that of satellite A, in orbit?

(d) By how much?
