# Why does the ruler rubbed on hair attract paper pieces?

Contents

Comb after going through dry hair developed some charges on it due to the frictional electricity . When this charged comb brought near to the piece of papers ,it induced charges of opposite charges on the nearer ends of the paper. This results in the attraction between comb and the paper.

## Why does a comb rubbed on hair attracts 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.

## What happens when you rub a ruler on your hair?

What is happening? Rubbing the ruler with a cloth transfers electrons from the cloth to the ruler so the ruler now has an excess of electrons and it is negatively charged.

## Why does plastic ruler attract pieces of paper when it is 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.

## 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.

## When you rub a comb with your 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 …

## When a comb is rubbed with dry hair both comb and paper get similarly charged?

Correct: A comb rubbed with hair and brought near pieces of r paper attracts them, because both have dissimilar charges.

## Why does plastic attract hair?

After being rubbed together, the plastic in the balloon picks up a negative charge, while the person’s hair ends up with a positive charge. … This attraction between oppositely charged objects is what we know as ‘static’.

## What happens when you rub a plastic ruler on your hair?

Shifting electric charges

The surface of the plastic ruler gets coated with the electrons rubbed off the atoms in the wool. The same effect is seen when you use a plastic comb on your hair. … Therefore, the Perspex rod will have an overall positive electric charge.

## 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.

## When plastic ruler is rubbed on hair develops force?

when the ruler is rubbed against dry hair , friction occurs between the two objects and electrostatic force is created.

## 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 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 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.
