When a plastic comb is rubbed with dry hair it attracts small pieces of paper demonstrate this experiment?

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 on dry hair attracts 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.

When a plastic comb is rubbed in dry hair it attracts tiny pieces of paper which force is involved in this process?

Electrostatic force is involved in this process.

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

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.

What happens when a comb is rubbed on dry hair?

When a comb rubhed with dry hair attracts pieces of paper. This is because the comb induces a net dipole moment opposite to the direction of field. This happens the field due to charge on comb induces dipole moment in paper by tretching or re-orienting molecules of the dielectric.

What happens when you rub a plastic comb on your hair?

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. … The charges move from one insulator to another on vigorous contact (i.e. by rubbing) to produce the two oppositely charged objects.

What happens when a comb rubbed against hair and is brought near the small pieces of paper?

Your hair must become positively charged in order to repel a negative charge. … 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.

What happens when the plastic comb is rubbed with a piece of cloth?

Because the plastic comb now has all these extra electrons stuck to it, it has an excess of negative electric charge. … When these materials are rubbed together, it is more likely that some of the electrons in the Perspex rod will be rubbed off by the atoms in the cotton cloth.

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?

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.
