Explanation:

When a plastic comb is dry hair, it becomes negatively charged. The negatively charged comb induces a positive charge on the pieces of paper which are neutral in nature. As we know that the unlike charges attract each other, plastic comb attracts tiny pieces of paper.

Answer 2

When we rub a plastic comb on dry hairs the friction between them results into production of static electric charge.

These charge of come creates negative charge and equal and opposite positive charge on paper due to which the magnetic force acts between comb and paper and paper get attracted.

hence, when we rub plastic comb with dry hairs the tiney or small pieces of paper get attracted towards each other.
