Two point charges are fixed on the y axis: a negative pointcharge q1 = -30 μC at y1 = +0.22 m and a positive point charge q2at y2 = +0.37 m. A third point charge q = +9.8 μC is fixed at theorigin. The net electrostatic force exerted on the charge q by theother two charges has a magnitude of 20 N and points in the +ydirection. Determine the magnitude of q2.
