Question

How is the force between two bodies affected if the distance between them is tripled?

Answer 1

Answer:

If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. ... If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

Answer 2

Answer:

If the distance between the two objects is tripled, then Thus, the gravitational force between the two objects becomes one-ninth. (iii) If the masses of both the objects are doubled, then Thus, the gravitational force between the two objects becomes 4 times.
