Three identical masses of 360kg each are placed on the x axis. One mass is at = -110cm , one is at the origin, and one is at = 450cm
Part A What is the magnitude of the net gravitational force on the mass at the origin due to the other two masses? Take the gravitational constant to be = 6.67×10?11 . Express your answer in Newtons.
Part B What is the direction of the net gravitational force on the mass at the origin due to the other two masses?
