How does a charged comb attract bits 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.

Which force makes a charged comb attracts small pieces of paper?

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.

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

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 is it possible that comb can attract pieces of paper?

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.

Why is paper attracted to a charged ruler?

When the negatively charged ruler is brought near to the paper pieces, they are attracted to the ruler as the the electrons move around on the paper because of the large charge on the ruler. Electrons will move away from the ruler leaving a positive charge on the paper near the ruler, so they are attracted.

Why do you think comb attracts some of your hair strands and papers?

Basically, when an electrification takes place, electrons are not created but they are transferred….. in the case of comb attracting tiny tiny bits of papers when rubbed with dry hair is because electrons from the dry hair gets transferred to the comb and now the comb induces a dipole in the bitties of paper and the …

What do you think is the charge of these bits 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.

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.

Why is a comb negatively charged?

When a comb is run through dry hair, the comb gets negatively charged due to friction. when the negatively charged comb is brought near a small bit of paper,the electron on the paper are repelled and positive charge will be nearer to the comb.

Is a comb positively or negatively charged?

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 do combs get charged?

These atoms contain equal number of protons and electrons so they are uncharged. So the surface of any object made of atoms has electrons, which are negatively charged. When the comb is rubbed against the cloth the electrons move between the two, and the comb gets charged.

How is an Electroscope charged by induction?

In the induction process of charging, a charged object is brought near to but not touching the electroscope. … With the charged object still held above the plate, the electroscope is touched. At this point electrons will flow between the electroscope and the ground, giving the electroscope an overall charge.

What is the difference between the charging of a comb and the charging of the paper bits?

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.

What happens when you rub a comb on a piece of wood?

We often comb longer with a wooden comb because it feels so good. The massaging action stimulates the follicles to produce more hair strands, increasing hair growth and producing thicker hair.

What does it mean when we say that the balloon comb is charged through rubbing?

When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. … Similarly, when you rub a balloon on your head it causes opposite static charges to build up both on your hair and the balloon.

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.
