Question: Four balls, each with mass m,are connected by four non conducting to form a square with side as shown in Figure. The assembly is placed on a horizontal, nonconducting, frictionless surface.Balls 1and 2each have charge q, balls 3and 4are uncharged. Find the maximum speed of balls 3and 4after the string connecting balls 1and 2is cut.
