Two spherical balls are placed so that their centers are 2.6 m apart. The force between the two balls is 2.65 10-12 N. What is the mass of each ball if one ball is twice the mass of the other ball?
_______ kg (lighter ball)
_______ kg (heavier ball)
I also just wanted to say thank you to all the Canadians willing to help, you are so much more helpful then any Americans!!

Newton's Law of Gravity
F = G m1 m2 / r^2
You know the Newton gravity constant, the force ( 2.65 x 10^-12 N ), the separation ( 2.6 m ) and that m2 = 2 m1. Plug it all in and solve for m1.

Gravitational force = G* m1*m2/r^2
You can solve for the product m1*m2, then use the relation of m1 = 2*m2 to get the individual masses.
This came from America!!
