6) A small charged plastic ball is vertically above another charged small ball in a frictionless test tube as shown in the figure. The balls are in equilibrium a distance 5cm apart. If the charge on each ball is tripled, and all other forces remain constant, the equilibrium distance between the balls in the test tube would become A) 10cm B) 15cm C) 30cm D) 45cm E) 8.66cm
