Physics

1.Three identical very dense masses of 3500 kg each are placedon the x axis. One mass is at x1 = -120 cm , one is at the origin,and one is at x2 = 300 cm .

What is the magnitude of the net gravitational force Fgrav onthe mass at the origin due to the other two masses?

Take the gravitational constant to be G = 6.67×10−11N⋅m2/kg2 .

Express your answer in newtons to three significant figures.
