Two uniformly charged insulating bars are bent in a semicircular shape with radius r = 10.0 cm. If they are placed so that they form a circle, but without touching, and have opposite charges of + 1.00μC and -1.00μC, find the magnitude and direction of the electric field in the center of the circular configuration composed of charges.
