Why does a comb run through wet hair not attract bits of paper?

Note:If the hair is wet, or if it is a rainy day, friction between the hair and the comb reduces. The comb does not get charged, and it will not attract small bits of paper. The important thing required to create electric charge in the comb is friction.

Why does a comb attracts bits of paper on rubbing in hair?

When the charged comb is brought near bits of paper, the electrostatic force of attraction between the atoms of the paper and the comb caused by the electrons on the surface of the comb polarizes them which attracts the pieces of paper towards the comb.

Why do some materials not attract pieces of paper even after rubbing?

Bits of paper are dielectric and get attracted through dielectrophoretic force. To attract bits of paper, there needs to be high electric field gradient. Rubbing creates an imbalance in number of protons and electrons.

Why does hair attract to a comb?

When a comb is run through your hair charges pass between your hair and the comb, so the comb becomes charged either positively or negatively, and the hair oppositely charged. When the comb is brought close to paper an opposite charge is induced in the paper, and the opposite charges attract.

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.

What happens to your hair after rubbing the comb balloon on it repeatedly how about the tissue paper?

When a rubber balloon is rubbed against human hair, electrons are transferred from the hair to the rubber, giving the balloon a net negative charge, and leaving the hair with a net positive charge.

Why did it repel quickly after it touched or stuck on the comb?

When the paper touches the comb, some of the excess negative charge in the comb is transferred to the paper. Because their charges are like, the paper is then repelled.

Why is the plastic scale or comb not able to attract pieces of paper before it gets rubbed by dry hair?

Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper. A charged body can attract an uncharged body.

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

This happens because when comb is rubbed with hair there occurs a transfer of electrons from hair to the comb. Thus the comb gets negatively charged,when the charged comb is brought near the bits of paper it attracts the positive part of it.

Why would torn paper be more attractive to the comb that cut paper?

Charge accumulates more easily on sharp points rather than edges. Torn pieces of paper have more sharp points (look at it under a magnifying glass, or better yet, a microscope!) compared to cut paper.

Why do tiny bits of paper get attracted?

Tiny bots of paper undergo electrostatic force , when you rub a comb or pen or anything which is plastic. Therefore they get attracted to the thing which you have rubbed.

When a comb is rubbed on dry hair it gets charged?

Complete step by step answer:irstly, when the comb is used to rub dry hair, it always acquires a negative charge or electron which the hair carries, where the comb is induced with the electron gotten from the hair then immediately the comb which is negatively charged comes in contact with the piece of paper which is …

What is the nature of the force involved while combing your hair?

This is due to the presence of electrostatic forces. … This happens because by rubbing charge get formed on the comb.

What force is used when combing your hair?

Electrostatic force is the force exerted by a charged body on another charged or uncharged body. Eg: Take a comb and brush it on a hair 3-4 times and then take it near some small bits of paper.
