A simple method for determining the secondary minimum distance and energy for two parallel plane surfaces interacting with constant potential and constant surface charge density in a symmetrical electrolyte solution is presented. Both cases are treated, namely, non-retarded and retarded interaction. Two graphics which provide a quick survey for determining the secondary minimum are reported.
