Answer:
Static electricity is generated at the tips of the plastic comb. When brought in close contact with pieces of paper, the plastic comb attracts the pieces of paper. This is because the plastic comb (after it is rubbed in dry hair) develops a charge that is the opposite of the charge on the pieces of paper. We know that opposite charges attract. Hence, the pieces of paper are attracted to the charged plastic comb.
