How does a charged ruler attracts small pieces of paper?

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.

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.

Why is paper attracted to a charged 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.

What is the effect of charge on small bits of paper?

The electrically charged glass rod exerts a force on the tiny pieces of paper and hence attracts them. A glass rod rubbed with silk acquires the ability to attract small, uncharged pieces of paper. The process of giving electric charge to an object is called charging the object.

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.

Why does a ruler attract pieces of paper?

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.

What force is acting on the pieces of paper before the ruler is brought close to them?

When the ruler is brought close to bits of paper, the attractive electric force accelerates the paper bits upward against the force of gravity.

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.

How do you Uncharge an object?

Grounding is the process of removing the excess charge on an object by means of the transfer of electrons between it and another object of substantial size. When a charged object is grounded, the excess charge is balanced by the transfer of electrons between the charged object and a ground.

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.

Why can a charged plastic ruler attract one a4 paper?

Shifting electric charges

The surface of the plastic ruler gets coated with the electrons rubbed off the atoms in the wool. … You can detect this overall negative charge on the atoms by the way the comb attracts the hairs on your hand or the way it attracts small pieces of paper.

How does an object get charged?

An object gets a charge when it is rubbed. This rubbing causes the objects to gain or lose electrons. When it loses electrons it becomes positively charged. When an object gains electrons it becomes negatively charged.

Why do tiny paper bits get attracted towards a plastic comb after the comb is rubbed against dry hair?

when plastic comb is rubbed with dry hair , it acquires charge due to static electricity and so it attracts pieces of paper which is uncharged.

What is meant by charging by friction?

Charging by friction: the transfer of electrons from one uncharged object to. another by rubbing the two objects together.
