Question

Find the electric potential energy for the following array of charges: charge q1 = +3.0 µC is located at (x, y) = (0.0, 0.0) m; charge q2 = +3.0 µC is located at (4.0, 3.0) m; and charge q3 = −1.0 µC is located at (0.0, 3.0) m.

Answer 1

Three point charges are arranged along the x-axis. Charge q1 = +4.25 µC is at the origin, and charge q2 = -6.25 µC is at x = 0.160 m. Charge q3 = -8.75 µC. Where is q3 located if the net force on q1 is 6.50 N in the −x-direction?
