Three point charges are on the x axis: q1 is at the origin, q2 is at x = +3.8 m, and q3 is at x = +5.1 m. Find the electrostatic potential energy of this system of charges for the following charge values. (Assume the potential energy is zero when the charges are very far from each other.)

(a) q1 = q2 = q3 = +2.7 µC


(b) q1 = q2 = +3.3 µC and q3 = -3.3 µC


(c) q1 = q3 = 3.8 µC and q2 = -3.8 µC

Three charges lie along the x-axis. One positive charge, q1 = 25 uC is at x = 0.25 m. Another charge, q2 = -5.0 uC, is located at the origin. A third charge, q3 = -35 uC, is placed so that q2 is in electrostatic equilibrium with q1 and q3. How large must the electrostatic force between q2 and q3 be to balance the force between q1 and q2?
