5. A plastic rod is rubbed with wool, producing a distribution of positive and negative surplus charge that is concentrated in two locations on the rod and two on the wool. This distribu- tion can be approximated as two pairs of small balls of charge as shown in Figure P26.5. The distance d is 30.0 mm, and the magnitude of the charge on each ball is 2.00 µC. If 34.0 J of work went into thermal energy as the rod and wool heated up, how much work was done on the system? Figure P26.5 2d- 2d- rod wool -
