Problem
Three identical point charges are fixed at the corners of an equilateral triangle of side length L. Initially all three charges are +q. Without doing calculations, describe qualitatively how the magnitude of the net electrostatic force on any one corner charge changes if the charge at one corner is replaced by −q while the other two remain +q.
