In Figure two curved plastic rods, one of charge + q and the other of charge ? q, form a circle of radius R = 8.50 cm in an xy plane. The x axis asses through both of the connecting points, and the charge are distributed uniformly on both rods. If q = 15.0pC, what are the?

(a) Magnitude and

(b) Direction (relative to the positive direction of the x axis) of the electric field E produced at P, the center of the circle?
