Question 15

The distance between a planet and its star varies from 1.4 × 1011 m at perihelion (closest point) to 1.6 × 1011 m at aphelion (furthest point). When the planet is at its closest point to the star, the magnitude of the gravitational force between them is FFF.

What is the gravitational force between them when they are at their furthest point apart?
