The gravitational force between two objects is 2400 N. What will be the gravitational force between the objects if the mass of one object is doubled?

Gravitational force is directly proportional to the mass of either object when the other mass and the distance between them stay the same. Doubling one object's mass doubles the force: 2,400 N × 2 = 4,800 N. Therefore, the correct choice is 4,800 N.
