Quizplus · Accepted Answer

According to Newton's Third Law of Motion, the force of gravity is always equal and opposite between two objects. Therefore, the force exerted on the satellite by the Earth is exactly the same magnitude as the force exerted on the Earth by the satellite. The mass of the objects does not affect this law.
