Question: the average distance from the moon to the center of...

Question details

The average distance from the Moon to the center of the Earth is 384,400 km, and the diameter of the Earth is 12,756 km. Calculate the gravitational force that the Moon exerts (a) on a 1-kg rock at the point on the Earth’s surface closest to the Moon and (b) on a 1-kg rock at a point on the Earth’s surface furthest from the Moon. The mass of the Moon is 7.349 × 1022 kg. (c) Find the difference between these two forces. This difference is the apparent tidal force from the Moon pulling the two rocks apart.
