In Fig., two curved plastic rods, one of charge +q and the other of charge -q form a circle of radius R = 4.25 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 = 15.0 pC, what are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the electric field vec(E) produced at P, the center of the circle ? |
