1. The problem statement, all variables and given/known data Two objects attract each other with a gravitational force of magnitude of 1*10^-8 N when separated by 20 cm. if the total mass of the two objects is 5kg, what is the mass of each. 2. Relevant equations Fg=G*m1*m2/r^2 3. The attempt at a solution i know everything that has to plugged into the equation, but the only part that is hard for me is that it gives you the total sum of the two objects and in the equation, you have to use the product of the masses. how can i change the formula to make it so that i can use the total sum instead of the product?
