A satellite in Earth orbit has a mass of 91 kg and is at an altitude of 1.97 x 10^6 m. (Assume that U = 0 as r %u2192 infinity .)
(a) What is the potential energy of the satellite%u2013Earth system?
(b) What is the magnitude of the gravitational force exerted by the Earth on the satellite?
(c) What force, if any, does the satellite exert on the Earth? (Enter the magnitude of the force, if there is no force enter 0.)
