Question

The gravitational force between two objects is 2000 N. The mass of each object is reduced to one-third of its original mass.

How must the distance between the objects change to keep the gravitational force between them 2000 N?

The distance must be one-ninth the original distance.
The distance must be one-third the original distance.
The distance must be three times greater.
The distance must be nine times greater.

Answer 1

The distance must be 1/3rd the original distance

Answer 2

The distance must be 1/3rd the original distance
