Q4-A semicircle of radius a is in the first and second quadrants, with the center of curvature at the origin. Positive charge +Q is distributed uniformly around the left half of the semicircle, and negative charge -Q is distributed uniformly around the right half of the semicircle (as shown in Fig.). What are the magnitude and direction of the net electric field at the origin produced by this distribution of charge?
