Question

Six artificial satellites complete one circular orbit around a space station in the same amount of time. Each satellite has mass m and radius of orbit L. The satellites fire rockets that provide the force needed to maintain a circular orbit around the space station. The gravitational force is negligible.
Rank the net force acting on each satellite from their rockets.

A) m = 200 kg and L = 5000 m
B) m = 400 kg and L = 2500 m
C) m = 100 kg and L = 2500 m
D) m = 100 kg and L = 10000 m
E) m = 800 kg and L = 5000 m
F) m = 300 kg and L = 7500 m
