Question

When dry hair is combed the comb acquired the property of attracting the small bits of paper why what happen if hair is wet

Answer 1

Answer:

When the comb runs through dry hair, it gets charged by friction. The molecules in the paper get polarized by the charged comb, resulting in a net force of attraction. If the hair is wet, or if it is a rainy day, the friction between the hair and comb reduces.
