Solve the all parts of given problem:
Problem: Three identical very dense masses of 5300kg each are placed on the x axis. One mass is at x1 = -120cm, one is at the origin, and one is at x2 = 310cm.
Part A: What is the magnitude of the net gravitational force F grav on the mass at the origin due to the other two masses?
Part B: What is the direction of the net gravitational force on the mass at the origin due to the other two masses?
Rework your solution from the beginning and check each step carefully to find the magnitude of the net gravitational force.
