Three identical very dense masses of 3700kgeach are placed on thexaxis. One mass is atx1= -150cm, one is at the origin, and one is atx2= 400cm.

A. 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 = 6.671011 Nm2/kg2 .

B.What is the direction of the net gravitational force on the mass at the origin due to the other two masses?
