1. The problem statement, all variables and given/known data Sphere A with mass 70 kg is located at the origin of an xy coordinate system; sphere B with mass 69 kg is located at coordinates (0.29 m, 0); sphere C with mass 0.40 kg is located at coordinates (0.15 m, 0.11 m). In unit-vector notation, what is the gravitational force on C due to A and B? 2. Relevant equations 3. The attempt at a solution I just have a quick question. How do you find distance between ac and bc. I know its simple i just don't wanna do the whole problem with wrong Rac and Rbc values. I graphed it and did Pythagorean theorem to find hypotenuse? Is this correct i got distance between ac to be .186 and bc to be .178. I got the physics down its the algebra that i need to check!
