A satellite in Earth orbit has a mass of 102 kg and is at an altitude of 2.10 106 m. (Assume that U = 0 as r ? ?.)
(a) What is the potential energy of the satellite-Earth system?
J
(b) What is the magnitude of the gravitational force exerted by the Earth on the satellite?
N
(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.)
N
