1. The problem statement, all variables and given/known data Three identical masses of 570 kg each are placed on the x axis. One mass is at x_1 = -10.0 cm, one is at the origin, and one is at x_2 = 43.0 cm. What is the magnitude of the net gravitational force F_grav on the mass at the origin due to the other two masses? Take the gravitational constant to be G = 6.67×10−11 N * m^2/kg^2. 2. Relevant equations F=G(m1m2/R^2) F=F1-F2 3. The attempt at a solution -(6.67*10^-11)*(570^2)/(-.1)^2 - (6.67*10^-11)*(570^2)/(.43)^2 =-0023 N What am i doing wrong?
