A thin plastic rod is bent into a semicircle of radius R centered at the origin. A charge - Qis uniformly distributed along the right half of the semicircle, while a charge of +Q is uniformly distributed along the left half of the semicircle, as shown in the figure. +Q R Q X Determine the net electric field at the origin due to the entire semicircle. Your answer must be a vector.
