Objects with masses of 285 kg and a 585 kg are separated by 0.390 m. Find the net gravitational force exerted by these objects on a 30.0 kg object placed midway between them. Then, at what position (other than infinitely remote ones) can the 30.0 kg object be placed so as to experience a net force of zero? I found the net gravitational force to be .000015798. The second part of the question is what I dont get. I tried F1-F2=0 and F2-F1=0 and setting them equal to each other so that .000000451/(.39-x)^2 = .000001491/x^2 but it didn't come out right.
