Problem
Two identical positive point charges are fixed 0.30 m apart on a horizontal line. A small positive test charge is placed exactly halfway between them and then given a very small displacement perpendicular to the line of the charges. Describe whether the midpoint is a point of stable, unstable, or neutral equilibrium for the test charge, and briefly state why.
