Two point charges are separated by some distance. The charge of the first is positive. The charge of the second is negative and its magnitude is twice as large as the first. eS 1) Is it possible find a place to bring a third charge in from infinity without changing the total potential energy of the system? YES, as long as the third charge is positive YES, as long as the third charge is negative YES, no matter what the sign of the third charge NO
