Problem
Two identical positive point charges are fixed at the ends of a straight 6 cm line segment. A small negative point charge is released from rest at the midpoint of the segment. Without performing any calculations, state whether the total electric potential energy of the three-charge system becomes more positive, more negative, or remains the same after the negative charge is in place, and briefly justify your answer.
