A small polyester ball is given a negative charge, q. A piece of polyvinyl chloride (PVC) pipe is given the same charge, concentrated at a point near one end. The ball is then placed over the PVC pipe, where it is observed to remain at rest 35 cm from the pipe. The mass of the polyester ball is 0.80 grams. Determine the charge on the ball in μC
