A satellite orbits a planet of unknown mass in a circle of radius 2.3 x 10^7 m. The magnitude of the gravitational force on the satellite from the planet is F = 62 N. (a) What is the kinetic energy of the satellite in this orbit? (b) What would F be if the orbit radius were increased to 3.0 x 10^7 m?
