4 charges are fixed to the corners of a square of side .53 cm. Charge 1 of -1 uC is fixed to the top left corner. Charge 2 of -2uC is fixed to the top right corner, charge 3 of 3uC is fixed to the bottom left corner , and charge 4 of -4uC is fixed to the bottom right corner. a) find the magnitude and direction of the electric field at the center of the square b) find the potential at the center c) find the electric potential energy of the system.
