A scientific spacecraft orbits a planet in a highly elliptical orbit. The distance from the centre of the planet to the spacecraft ranges from a minimum of 3.8 × 106 m at periapsis (closest point) to a maximum of 9.5 × 106 m at apoapsis (furthest point). When the spacecraft is at apoapsis, the gravitational force exerted on it by the planet is FFF.
What is the magnitude of the gravitational force exerted on the spacecraft when it is at periapsis?
