A)directly with the cube of the distance between the objects.
B)directly with the square of the distance between the objects.
C)directly with the square of the distances of the objects divided by the product of the masses.
D)inversely with the cube of the distance between the objects.
E)inversely with the square of the distance between the objects.

Question

Quizplus · Accepted Answer

The tide-generating force is a type of gravitational force, which decreases with the square of the distance between the objects. Additionally, the force is inversely proportional to the cube of the distance due to the fact that the volume of a sphere increases with the cube of its radius. Therefore, D is the best choice as it takes both of these factors into account.
