In the figure two curved plastic rods, one of charge +q and the other of charge -q, form a circle of radius R = 8.58 cm in an xy plane. The x axis passes through both of the connecting points, and the charge is distributed uniformly on both rods. If q = 14.7 pC, what is the magnitude of the electric field produced at P, the center of the circle? +q Ø P
