A satellite of mass \( M \) moves in a circular orbit of radius \( R \) at a constant speed \( v \). Which of the following must be true? I. The net force on the satellite is equal to \( M v^{2} / R \) and is directed toward the center of the orbit. II. The net work done on the satellite by gravity in one revolution is zero. III. The angular momentum of the satellite is constant. I only III only I and 11 only II and III only I. II and iII
