A -4.00 nC point charge is at the origin, and a second -5.00 nCpoint charge is on the x-axis at x = 0.800 mm.
a. Find the net electric force that the two charges would exerton an electron placed at point on the x-axis at x = 0.200 mm.
b. Find the net electric force that the two charges would exerton an electron placed at point on the x-axis at x = 1.20 mm.
c. Find the net electric force that the two charges would exerton an electron placed at point on the x-axis at x = -0.200 mm.
