As shown in Fig. 21–2Solutions Manual For Physics for Scientists & Engineers with Modern Physics (Volume 2) 5e (Global Edition) By Douglas C. Giancoli-1. Suspend a plastic ruler by a thread and then rub it with a cloth. As shown in Fig. 21–2a, the ruler is negatively charged. Now bring the charged comb close to the ruler. If the ruler is repelled by the comb, then the comb is negatively charged. If the ruler is attracted by the comb, then the comb is positively charged. 2. The shirt or blouse becomes charged as a result of being tossed about in the dryer and rubbing against the dryer sides and other clothes. When you put on the charged object (shirt), it causes charge separation within the molecules of your skin (see Fig. 21–9), which results in attraction between the shirt and you
