5. The figure shows four configurations of four charges, each charge having charge +q or -q, placed at the corners of a square. Rank the configurations in terms of the applied work required to place an electron, initially at infinity, at the center of each square, from most positive value of applied work to most negative value. A B C D (1) B=C> D> A (2) A> D> B=C (3) C>D> A=B (4) A=B> D > C (5) A= B= C>D
