Question

Three identical very dense masses of 4100 kg each are placed on the x axis. One mass is at x1 = -140 cm , one is at the origin, and one is at x2 = 350 cm . 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?11 N?m2/kg2 . Express your answer in newtons to three significant figures. Part B) What is the direction of the net gravitational force on the mass at the origin due to the other two masses? X or Y direction?
