Which is not a way to increase the gravitational force between the two objects in the picture? Increase the distance between the objects; decrease the distance between the objects; increase the mass of both objects; none of the options above)

Answer 1

To increase the gravitational force between two objects, you should decrease the distance between them and/or increase the mass of either or both objects. Therefore, "increase the distance between the objects" is not a way to increase the gravitational force.

So, the correct answer is: increase the distance between the objects.
