Why does a plastic comb attract paper when rubbed on dry hair?

Initially, the comb is electrically neutral. When the comb is rubbed on a dry cloth, it gets electrically charged. This charged comb exerts an electric force on the tiny pieces of paper and attracts them.

Why does a rubber comb attract bits of paper?

Comb attracts a bits of paper because Comb is charged object and paper is in neutral so, to be charged one must be in neutral and Comb is negative charged as it gains electrons from hair. Since ,when Comb is placed near to a bits of paper then papers get charged due to induction.

Why does plastic comb gets electrified on combing dry hair?

Plastic comb is poor conductor of electricity so they contain static charges. While rubbing, due to friction,these static charges gain energy and get electrified. Whereas metal do not contain static charges as they are good conductors of electricity.

What happens when a plastic comb rubbed several times in dry hair is brought near a heap of pieces of paper?

Answer: Within the papers strips, the electrons get either repelled or attracted according to whether the comb has a negative or a positive charge. This makes the paper strips have an unlike charge in the direction of the comb, and makes them rise towards it.

What interesting thing happens if you rub a plastic pen on your shirt and then move the pen near a piece of dust or a small piece of paper?

ANSWER: They have been charged by contact as they rub against other clothes, and thus, are attracted to clothing that is neutral or has an opposite charge.

Why does a plastic comb rubbed with dry hair attract tiny pieces?

Why does a plastic comb rubbed with dry hair attract tiny pieces of paper? Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper. A charged body can attract an uncharged body.

Why does a plastic comb attract bits of paper?

If we bring bits of paper near a 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 when we rub the comb over dry hair the attractive property develop in the comb due to Friction.

Why is a plastic comb an insulator?

because of electrostatic forces acting on it. when we rub the plastic comb it will either be charged negatively or positively. it will induce negative charges on the bits of paper if the comb is positively charged so, the bits of paper will be attracted by the plastic comb which is an insulator. share|cite|improve this answer.

What is the charge of a rubbing comb on a paper?

It acquires a negative charge due to the movement of electrons from hair to comb. So when we put the rubbing comb over the pieces of paper which is neutral the positive charge induce at the end of paper and negative charge at the other end.
