# Quick Answer: Why does charged plastic attract paper?

Contents

This is because a charged object can attract an uncharged insulator. For example, a negatively charged plastic object such as a comb or ruler repels electrons in a piece of paper. The near side of the paper to the plastic object becomes positively charged, so it is attracted to the plastic object.

## Why is paper attracted to a charged rod?

The bits of paper become polarized because the atoms in the paper have formed dipoles. The side close to the charged rod has the opposite charge as the rod, thus is attracted to the rod.

## Why do bits of paper get attracted to a charged plastic comb?

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 plastic rod become negatively charged?

When a polythene rod is rubbed with a duster, the friction causes electrons to gain energy. Electrons gain enough energy to leave the atom and ‘rub off’ onto the polythene rod. The polythene rod has gained electrons, giving it a negative charge.

## Is plastic positively or negatively charged?

When a plastic rod is rubbed with a cloth, the plastic rod becomes negatively charged as electrons from the cloth are deposited on the plastic rod.

## Why does static electricity attract plastic?

Since plastics are insulators, they are poor conductors of electricity. Electrical charges tend to build up on the surface of insulators resulting in static electricity.

## What happens when you place the charged plastic sheet over pieces of paper?

Put the torn-up paper on your table and then bring your charged tape over them. Here’s what happens. The charged paper attracts the neutral paper. … When it comes near the neutral paper, the negative tape pushes on the negative charges in the paper and pulls on the positive charge.

## How does a plastic scale attract paper?

The plastic scale gets electrically charged due to rubbing against dry hair. The plastic scale acquires charge due to static electricity. … The electrically charged scale exerts an electric force against the paper bits and attracts them.

## 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 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 plastic charged?

Explanation: When you rub plastic, you transfer electrons from one material to the other. … Because plastic is an insulator, the electrons cannot flow through it so they effectively get stuck there – they are static.

## Why does a rubbed plastic rod attract a stream of running water?

When a negatively-charged rod is brought close to a water stream, individual water molecules align themselves so the positive (hydrogen) end points towards the rod. Negative and positive charges attract one another and the water stream is bent towards the rod.
