Question

if the distance of separation begin two objects is doubled, is the gravitational force between the objects increased or decreased? by what factor?

Answer 1

force is decreased by a factor of 4.

Step-by-step explanation:

According to the Newton's law of gravitation, the force of gravitation between the two object is inversely proportional to the square of distance between them. Now the distance is doubled, so the force between the two objects becomes one forth.

Force is decreased by a factor or 4.
