Three charges are arranged on the vertices of an equilateral triangle whose sides have length d = 0.1m, as shown below. In the picture, Q represents 100 nC, so the individual charges are +100 nC, +200 nC, and -300 nC (recall that nC is 109 Coulombs). What is the change in the potential energy of the system if we remove the +100 nC charge-that is, if we move the +100 nC charge very far away from the other two charges? A. PE increases by 0.9 mJ B. PE decreases by 4.5 mJ C. PE increases by 4.5 mJ D. PE does not change E. PE decreases by 0.9 mJ +20 -30
