•• Four point charges are located at the corners of a square with sides of length a. Two of the charges are +q, and two are -q. Find the magnitude and direction of the net electric force exerted on a charge +Q, located at the center of the square, for each of the fol- lowing two arrangements of charge: (a) The charges alternate in sign (+q, −q, +q, — q) as you go around the square; (b) the two pos- itive charges are on the top corners, and the two negative charges are on the bottom corners.
