Chapter 18, Problem 13
Two point charges are fixed on the y axis: a negative point charge q1 = -26 μC at y1 = +0.17 m and a positive point charge q2 at y2 = +0.35 m. A third point charge q = +9.5 μC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two charges has a magnitude of 26 N and points in the +y direction. Determine the magnitude of q2.
