Consider two point charges located on the x axis: one charge, q_1 = -14.5 nC, is located at x_1 = -1.700 m; the second charge, q_2 = 36.5 nC, is at the origin (x=0.0000).
What is the net force exerted by these two charges on a third charge q_3 = 46.5 nC placed between q_1 and q_2 at x_3 = -1.070 m?
