###### Question:

My teacher is not very helpful, so please write cleanly and explain your steps so I can learn. At the end, please summarize formulas used.

===================================

Three identical very dense masses of 7400 kg each are placed on the x axis. One mass is at x1 = -110 cm , one is at the origin, and one is at x2 = 340 cm .

===================================

Part 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 = 6.67×10−11 N⋅m2/kg2 .
