Problem
A satellite of mass m experiences a gravitational force F0 from a planet when orbiting at a distance R from the planet’s center. After several maneuvers, the satellite’s mass has decreased by 15% and its orbital radius has been reduced to 0.70R. Determine the factor by which the gravitational force on the satellite has changed compared with F0, and state whether the force increases or decreases.
