Two objects are attracted to each other by gravitational forces. Suppose I double the mass of one of the objects. This changes the gravitational forces between them. I can make this force the same as it was at first, however, by

A$.$

increasing the distance between the two objects.

B$.$

decreasing the distance between the two objects.

C$.$

increasing the mass of the other object.

D$.$

doing nothing; the force is not changed unless I change the mass of both objects, since the gravitational force depends on both these masses.

E$.$

either decreasing the distance between the objects or increasing the mass of the other object.
