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 7520 kilometer. Satellite B is to orbit at an altitude of 15100 kilometer. The radius of Earth RE is 6370 kilometer.
(a) Find the ratio of the potential energy of satellite B to that of satellite A, in orbit?
(b) Find the ratio of the kinetic energy of satellite B to that of satellite A, in orbit?
(c) Find which satellite has the greater total energy if each has a mass of 23.2 kilogram?
(d) By how much?
