Why do combs attract 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 do tiny bits of paper get attracted?

Tiny bots of paper undergo electrostatic force , when you rub a comb or pen or anything which is plastic. Therefore they get attracted to the thing which you have rubbed.

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.

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.

THIS IS IMPRESSING:  Frequent question: Do you have to be pretty to be attractive?

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.

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 …

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.

Why would torn paper be more attractive to the comb than 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 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.

THIS IS IMPRESSING:  You asked: How long does it take to grant Australian student visa?

Why do tiny bits of paper get attracted when brought close to comb?

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 instrument detects electric charge?

electroscope, instrument for detecting the presence of an electric charge or of ionizing radiation, usually consisting of a pair of thin gold leaves suspended from an electrical conductor that leads to the outside of an insulating container.
