The new gravitational force is 12 times smaller than the old one

• D.

The new gravitational force is 24 times smaller than the old one

• 4.
The gravitational force between two objects (mass1 = 10kg, mass2 = 6kg) is measured when the objects are 12 centimeters apart.  If the distance between them is increased to 36 centimeters, how does the new gravitational attraction compare to the first one that was measured?
