Question: Three identical very dense masses of 5200kg each are placed on the xaxis. One mass is at x1 = -110cm , one is at the origin, and one is at x2 = 310cm .
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
