1. The problem statement, all variables and given/known data When the distance separating two masses, M and m, is 1.2 x 10^10 m, the gravitational force of attraction is 5.0 N. If the mass of M becomes 3M and the separation distance becomes 2.4 x 1010 m, what will be the force? 2. Relevant equations Fg=MaMb/r^2 3. The attempt at a solution since i have r and Fg (first part of question) i tried solving for the masses. but how do i solve for both when i need at least one to solve the other/??
