Why does a plastic comb rubbed with dry hair attract bits 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.

When we rub a plastic scale with dry hair it attracts the paper bits of paper which force is responsible for this?

The correct answer is Negative charge. A plastic scale after being rubbed against dry hair attracts bits of paper as it acquires a negative charge. The plastic scale gets electrically charged due to rubbing against dry hair. The plastic scale acquires charge due to static electricity.

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.

When a plastic comb is rubbed with dry hair?

When a plastic comb is rubbed against dry hair vigorously, then there is a transfer of charge taking place between the two. As a result, both objects become charged. While one becomes positively charged, the other becomes negatively charged. This is called charging by friction.

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.

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 a plastic comb comb your dry hair and it bring near small pieces of paper the comb attracts pieces of paper why and how?

When we comb our hair, it gets positively charged by rubbing. When the comb is brought near the pieces of paper some of the electrons accumulate at the edge of the paper piece which is closer to the comb. At the farther end of the piece there is deficiency of electrons and hence, positive charge appears there.

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.

When a comb is rubbed with dry hair both comb and paper get similarly charged?

Correct: A comb rubbed with hair and brought near pieces of r paper attracts them, because both have dissimilar charges.

Why would torn paper be more attractive to the comb than 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.

When a comb is rubbed against hair the comb attracts the bits of paper why Class 8?

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. When the paper touches the comb, some of the excess negative charge in the comb is transferred to the paper.

What happens to the hair after combing plastic comb several times?

If you comb your hair, for example, electrons leave the atoms and molecules in your hair and travel to the plastic comb. The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. … Shocks come from gaining or losing electric charge in a hurry.

Why in winter season a plastic comb after being used for combing dry hair attracts pieces of paper that are electrically neutral?

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