Question

Two point charges are fixed on the y axis: a negative pointcharge q1 = -26 µC at y1 = +0.24 m and a positive point charge q2at y2 = +0.32 m. A third point charge q = +7.5 µC is fixed at theorigin. The net electrostatic force exerted on the charge q by theother two charges has a magnitude of 29 N and points in the +ydirection. Determine the magnitude of q2.

Thanks for helping!!!!!!!!!!!!
