1. The problem statement, all variables and given/known data
Three identical very dense masses of 8000kg each are placed on the x axis. One mass is at x1 = -140cm , one is at the origin, and one is at x2 = 440cm . What is the magnitude of the net gravitational force Fgrav on the mass at the origin due to the other two masses?
Take the gravitational constant to be G = 6.67×10−11N⋅m2/kg2 .
2. Relevant equations
F=G(m1m2/r^2)
3. The attempt at a solution
I have tried everything, but Mastering Physics still gives me this message: Although the two masses not at the origin are identical, they are not the same distance from the origin, so there will be a nonzero net force on the mass at the origin. Am I adding the vectors wrong? I got 2.1*10^-3
