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?
