# How can a charged plastic comb attract neutral pieces of paper?

Contents

Objects can get charged when rubbed together with different objects. When you run a plastic comb through your hair, the comb gets charged due to friction – the plastic loses some electrons. Then when you place the comb near small pieces of paper, the paper pieces are attracted to the comb.

## How can a charged comb attract neutral pieces of paper?

You can observe static electricity if you run a plastic comb through your hair, then place the comb near small pieces of 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.

## Why does a charged comb attract paper bits?

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 does paper being neutral is still attracted by charged plastic scale?

6 Answers. This is because the neutrality of polarity can be changed by electric field in this case. When you create – charge in the comb and you expose the pieces of paper to the electric field created by the charge, you will polarise them so that the part closer to the comb will be + and the other will be -.

## How do you charge a plastic comb?

If you hold a plastic comb in your hand and rub it in your hair, it will get charged. However, if you do the same with a metal comb it will not get charged. Why? But if the metal comb has a plastic handle and you hold it from the handle, it will also get charged.

## How will you charge a plastic comb by the method of friction?

Due to this attraction, the tiny pieces of paper move towards the comb and stick to it. Actually, when we rub the plastic comb with our dry hair, the plastic comb gets electric charge due to friction. The electrically charged comb then exerts an electric force on the tiny pieces of paper and attracts them.

## Why does it attract pieces of paper after swirling a comb through 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.

## Why do tiny bits of paper get attracted when brought close to a plastic comb rubbed with 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.

## Why does a plastic comb rubbed with dry hair attracts tiny pieces of paper class 8?

When a plastic comb is dry hair, it becomes negatively charged. The negatively charged comb induces a positive charge on the pieces of paper which are neutral in nature. As we know that the unlike charges attract each other, plastic comb attracts tiny pieces of paper.

## What happens when you comb your hair with a plastic comb?

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.

## What is the charge of your hair if you comb your hair and the comb become positively charged?

The material that gains electrons becomes negatively charged while the material losing electrons becomes positively charged. The comb is positively charged implying the hair should be negatively charged. If you comb your hair and the comb becomes positively charged, then your hair becomes negatively charged.

## 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.

## What is the charge of paper?

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.
