Four point charges are arranged in a rectangle of length x and width y as shown in the figure. Two charges are positive and two are negative, but all have the same magnitude Q. How much energy (delta U) is required to disassemble the configuration of charges so that each charge is far away from all the others? Express your answer in terms of x, y, Q, and the Coulomb force constant k.
