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 of the net electric force exerted on a charge +Q, located at the center of the square, for the following arrangement of charge: the charges alternate in sign (+q,-q,+q,-q) as you go around the square.

Find the direction of the net electric force exerted on a charge +Q, located at the center of the square, for the following arrangement of charge: the charges alternate in sign (+q,-q,+q,-q) as you go around the square.

Find the magnitude of the net electric force exerted on a charge +Q, located at the center of the square, for the following arrangement of charge: the two positive charges are on the top corners, and the two negative charges are on the bottom corners.

Find the direction of the net electric force exerted on a charge +Q , located at the center of the square, for the following arrangement of charge: the two positive charges are on the top corners, and the two negative charges are on the bottom corners.
