Does a metal rubbed hair attract pieces of paper?

with plastic scale it is possible, because rubbing it with your hair generates static electricity – as plastic is a bad conductor of electricity. where as metal scale absorbs electrons and hence it doesn’t generate that effect. Bits of paper are dielectric and get attracted through dielectrophoretic force.

Does metal attract paper?

Charged objects attract both metal and paper, in fact they will attract metal more due to the delocalised electrons as opposed to electrons just repelling or attracting within their shells, as the latter doesn’t induce charges, but just distorts them.

Can a metal comb attract paper?

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.

Why does a comb rubbed on 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.

Is paper positively or negatively charged?

The bits of paper are electrically neutral, but when you bring the rod close to them, even though paper is not a conductor, that is, the charges within it are not free to move about as a current, the negative charges have enough mobility that they are repelled by the rod.

What happens when amber is rubbed with fur?

Thus, when amber is rubbed with fur, electrons are transferred from the fur to the amber, giving the amber an excess of electrons, and, hence, a negative charge, and the fur a deficit of electrons, and, hence, a positive charge.

When a comb is rubbed in your hair it acquires?

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 …

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 is hair attracted to comb during a hot day?

The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. … If two objects have different charges, they attract (or pull towards) each other.

Why do apples not repel each other?

Every apple contains equal numbers of negative and positive charges, therefore they appear neutral to each other.

When a comb is rubbed on dry hair it can attract pieces of paper without touching them this is due to <UNK>force?

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.

What happens when a dry metal comb is rubbed through dry hair?

Answer: Explanation: Nothing will happen because metal comb will not charge while rubbing with dry hair as compared to plastic comb.

Which of the following will attract bits of paper on being rubbed with hair?

Comb gets charged by friction and attracts bits of paper.

Is hair positively charged?

Hair naturally has a negative charge — sort of like static electricity — says Thomas, but this is insulated by our hair’s protective lipid layer. Damaged hair has higher negative charge, and the hairs literally try to separate from each other, creating frizz.

What did you do to make your hair or the pieces of paper stick to the balloon?

When two objects – such as your hair and the balloon – rub together, one loses some of its electrons to the other. This makes one object positively charged and the other object negatively charged. The opposites then are attracted to each other. The balloon is charged by rubbing it on your hair.

What happens when you bring the balloon near your hair after rubbing it?

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.)
