Problem 5 Four charges of equal magnitude (two positive and two negative)are placed on the corners of a square as pictured at left (positive charges at positions A &B,negative at positions C& D). You decide that you want to swap charges B C so that the charges of like sign will be on the same diagonal rather than on the same side of the square. In order to do this,you must do... 1. ..positive work 2. ..negative work 3. ..no net work 4. ..an indeterminate amount of work,as it depends on exactly how you choose to move the charges. Answer 2.By moving like sign charges farther apart and opposite sign charges closer together you reduce the energy of the system5 Problem 5 Four charges of equal magnitude (two positive and two negative) are placed on the corners of a square as pictured at left (positive charges at positions A & B, negative at positions C & D).
