Why does comb get charged when rubbed with hair?

Why does comb get charged when rubbed with hair?

This happens because the charged comb induces an opposite charge in the paper and as opposite charges attract, the paper sticks to the 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.

Is rubbing charging by friction?

When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be ‘rubbed off’ one material and on to the other. The material that gains electrons becomes negatively charged.

When you rub a comb through your hair what charge will the comb have?

negatively charged
One piece of tape therefore has extra negative charges. The other piece, which has lost some negative charge, now has an overall positive charge. Because opposite charges attract, the two pieces of tape attract each other. When you run a plastic comb through your hair, the comb becomes negatively charged.

Why does comb rubbed on hair attract 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. When the paper touches the comb, some of the excess negative charge in the comb is transferred to the paper.

What is the example of charging by rubbing?

Examples: When a piece of amber, plastic, polythene, or hard rubber is rubbed with fur, electrons are transferred from fur to the other material. Fur acquires net positive charge, since it has fewer electrons than protons.

What is the charge on the comb?

The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. This “separation of charge” is the reason for the collection of effects we call static electricity. If two objects have different charges, they attract (or pull towards) each other.

What happens when a balloon is rubbed on hair?

Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged. Like charges repel (the two balloons, once charged, will move away from each other) and opposite charges attract (the paper will be attracted to the charged balloons.)

Why comb acquire negative charge on rubbing with dry hair?

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 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 your hair with a comb?

When we rub our hairs with a comb, and then try to attract small pieces of paper, they’re attracted by the comb. The pieces of the paper were not electrified before they were attracted. Then they might be neutral.

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

When a comb rubbed with dry hair attracts pieces of paper. This is because the It is found that a charged object, whether positive or negative, may attract uncharged objects. This is because the comb gets charged when it is rubbed.This charge that is created when two objects are rubbed against each other is called static electricity

Can You charge a comb with a piece of wood?

No. Charging by friction requires for one substance to easily give up electrons on being rubbed (in this case hair) and the other substance to hold onto the electrons offered to it (in this case comb). In the case of wood, it does not have nearly as many electrons available for sharing as hair (rather negligible)…

Is it possible to charge a comb with hair?

No. Charging by friction requires for one substance to easily give up electrons on being rubbed (in this case hair) and the other substance to hold onto the electrons offered to it (in this case comb).
