Why are neutral pieces attracted to the charged comb?

The paper is attracted to the comb. This happens because the charged comb induces an opposite charge in the paper and as opposite charges attract, the paper sticks to the comb. The charges move from one insulator to another on vigorous contact (i.e. by rubbing) to produce the two oppositely charged objects.

How a charged comb can attract neutral pieces of paper does this contradict Coulomb’s law?

6 Answers. This is because the neutrality of polarity can be changed by electric field in this case. When you create – charge in the comb and you expose the pieces of paper to the electric field created by the charge, you will polarise them so that the part closer to the comb will be + and the other will be -.

Why does a comb rubbed on hair attracts small pieces of paper?

Initially, the comb is electrically neutral. So it has no effect on the tiny pieces of paper. 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.

Does the attraction between the rubbed comb and the pieces of papers last long Why?

Does the attraction between the comb and the piece of papers last for longer period of time? No, because the comb loses its net charge after some time. The exess charge of the comb transfers to earth through our body after some time.

Why do combs get charged?

These atoms contain equal number of protons and electrons so they are uncharged. So the surface of any object made of atoms has electrons, which are negatively charged. When the comb is rubbed against the cloth the electrons move between the two, and the comb gets charged.

When we comb our dry hair the hair attracts to comb the force involved in this is?

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.

Do you think a metallic aluminum comb can attract the pieces of paper?

ANSWER: The paper is initially attracted to the comb because the comb causes separation of charge in the paper. The part of the paper pieces with positive charge is attracted to the comb.

Why does a plastic comb rubbed with dry hair attracts tiny pieces of paper class 8?

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.

Why does a comb run through dry hair attracts small bits of paper what happens if the hair is wet?

This is because the comb gets charged by friction. Comb gets electrically charged by friction. Due to electric charge, paper gets polarized and it attracts small bits of paper. But when the comb runs through wet hair no electric charge is produced because friction between hair and comb is reduced.

What happened to the bits of paper place near the comb after using it why do you say so?

If you bring a charged comb near tiny pieces of paper, the pieces will first be attracted to the comb, but after touching they will fly away. Why do they fly away? SOLUTION: The paper is initially attracted to the comb because the comb causes separation of charge in the paper.
