Question

how comb attracts paper small pieces ​

Answer 1

Answer:

If we bring bits of paper near a rubber or plastic comb, the comb does not attract the bits of paper but if it is first rubbed on dry hairs and then brought near the paper pieces it attracts.The reason is that the comb on rubbing over dry hairs gets charged and thus an attra ctive property is developed in the comb due to friction.
