In the equation for the gravitational force between two objects, which quantity must be squared?

The distance between the objects.

Explanation: The equation for the gravitational force is written as:

F = G*m1*m2/r^2

Where r is the distance between the objects, m1 and m2 are the masses and G is the gravitational constant.

This cuantity is in the denominator because, as larger is the distance, smaller is the strenght of the field.

And is squared because is a force that spreads in a solid angle (as the change of area in a growing sphere )

before we can answer, we have to see the choices that are printed there with the question.   that's the only way we can point you to the correct one.
