Question 36

A research satellite is in a highly eccentric orbit around a gas giant planet. The distance between the center of the planet and the satellite varies from a minimum of 2.4 × 109 m at periapsis (closest approach) to a maximum of 3.6 × 109 m at apoapsis (furthest point). When the satellite is at its periapsis, the gravitational force exerted on it by the planet is FFF.

What is the gravitational force exerted on the satellite when it is at its apoapsis?
