The diagram above shows two celestial bodies with the same mass, M, placed a distance, D, apart. What would increase the gravitational force between the two bodies?

1.Maintaining M and increasing D
2.Decreasing M and maintaining D
3.Decreasing M and increasing D
4.Increasing M and decreasing D

4. Increasing M and decreasing D

The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Therefore, increasing the mass of the objects and decreasing the distance between them would increase the gravitational force between them.
