A semi-circular, insulating rod has radius R and lies in the xy-plane. It carries a total charge Q. The center of curvature (i.e., the center of the circle of which this is a part) is at the origin, and the rod itself is in the first and second quadrants. Find the electric field vector produced by this charge distribution at the origin.
