Question

1. How does the gravitational force between two masses change if the separation between
them is halved and both the masses are doubled.​

Answer 1

So as two objects are separated from each other, the force of gravitational attraction between them also decreases. If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power).
