(a) How far must the ball be lowered to reach its equilibrium position?

(b) The ball is given a charge of 0.060 C. If an electric field directed upward is applied, increasing slowly to a maximum value of 270.0 N/C, how far below the unstretched position is the new equilibrium position of the ball?
