Question

2. A comb ran through one's hair attracts small bits
of paper, Why? What happens, if the hair is wet
or if it is rainy day?​

Answer 1

Answer:

it is due to due charge b/w comb and hair while in the wet clamatic conditions it is bheave like a barrier

Answer 2

Answer:

Comb gets electrically charged by friction when even through dry hair. It attracts small bits of paper because paper gets polarized in the presence if charged comb resulting in a net force of attraction. When hair is wet, the friction between comb and hair decreases and comb does not get charged. Hence, it may not attract small bits of paper.
