a charged comb often attracts small bits of dry paper that then fly away when they touch the comb. explain why?

Sagot :

When the comb is charged, it could be that the small bits of dry paper fly away because the small bits of dry paper and comb have the same charge causing them to fly away. Like charges repel and opposite charges attract. But if the comb still did not touch the small bits of dry paper, there was a slight attraction because there were opposite charges that time.
