Review | Constants 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. Three identical very dense masses of 3300 kg each are placed on the x axis. One mass is at a1 = -110 cm , one is at the origin, and one is Express your answer in newtons to three significant figures. at 12 = 340 cm . View Available Hint(s) ? Xb Vx Vx x IXI X . 10n X Fgrav = 1.14 . 10-5 N Submit Previous Answers X Incorrect; Try Again; 4 attempts remaining Although the two masses not at the origin are identical, they are not the same distance from the origin, so there will be a nonzero net force on the mass at the origin. Part B What is the direction of the net gravitational force on the mass at the origin due to the other two masses? O +x direction O -x direction
