Unformatted text preview: 3. Four balls, each with mass m , are connected by four non-conducting, massless strings to form a square with side a . The assembly is placed on a horizontal, non-conducting, frictionless surface. Balls 1 and 2 each have charge q . Balls 3 and 4 are uncharged. Find the maximum speed of balls 3 and 4 after the string connecting balls 1 and 2 is cut. At what time this maximum speed is reached?...
