Two point charges are fixed on the y axis: a negative point charge q1 = -34 μC at y1 = +0.19 m and a positive point charge q2 at y2 = +0.32 m. A third point charge q = +8.9 μC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two charges has a magnitude of 23 N and points in the +y direction. Determine the magnitude ofq2.

1. Oh! From your "school subject", I thought maybe you need help wiping your nose or tying your shoes. Is this physics?
