Three identical masses of 800 each are placed on the x axis. One mass is at = -10.0 , one is at the origin, and one is at = 44.

Three identical masses of 800 each are placed on the x axis. One mass is at = -10.0 , one is at the origin, and one is at = 44.0 . What is the magnitude of the net gravitational force on the mass at the origin due to the other two masses?
