Which force attracts the pieces of paper to a plastic comb?

Initially, the comb is electrically neutral. So it has no effect on the tiny pieces of paper. When the comb is rubbed on a dry cloth, it gets electrically charged. This charged comb exerts an electric force on the tiny pieces of paper and attracts them.

Does the attraction between the comb and the piece of paper last for long?

Does the attraction between the comb and the piece of papers last for longer period of time? Solution: Solution: No, because the comb loses its net charge after some time. The exess charge of the comb transfers to earth through our body after some time.

Why does plastic comb 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 does a plastic comb attract hair?

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 Cannot we attract pieces of paper with a comb after combing wet hair?

Comb attracts a bits of paper because Comb is charged object and paper is in neutral so, to be charged one must be in neutral and Comb is negative charged as it gains electrons from hair. Since ,when Comb is placed near to a bits of paper then papers get charged due to induction.

Why does it attract pieces of paper after moving 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.

What force exists between an uncharged object and a charged object?

The electric force is a non-contact force. Any charged object can exert this force upon other objects – both charged and uncharged objects. One goal of this unit of The Physics Classroom is to understand the nature of the electric force.

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 …

Why does a comb rubbed against dry hair attracts pieces of paper?

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.

Why does it attract pieces of paper after swirling a comb through dry hair?

Why does a plastic comb rubbed with dry hair attracts tiny pieces of paper class 8?

When a plastic comb is dry hair, it becomes negatively charged. The negatively charged comb induces a positive charge on the pieces of paper which are neutral in nature. As we know that the unlike charges attract each other, plastic comb attracts tiny pieces of paper.

Why does a plastic comb attract pieces of paper?

It is because plastic is not a good conductor of electricity. It does not allow the electric charges to flow through it onto the earth. As a result, the charges build in the plastic comb, making it electrically charged and enabling it to attract the pieces of paper.

Why is the attraction between a charged comb and paper Weak?

The attraction between a charged comb and neutral pieces of paper is very weak because it is due to a samml deformity induced in the atom. Atoms /molecules in paper will have theri electrons distributed pretty symmetrically around the nuclei.

Why is a plastic comb a good conductor of electricity?

It does not allow the electric charges to flow through it onto the earth. As a result, the charges build in the plastic comb, making it electrically charged and enabling it to attract the pieces of paper. However, metal is a good conductor of electricity. It does not let the charges build in it.

What happens when you rub a plastic comb on your hair?

When we rubbed the plastic comb on our dry hair, it gained an electric charge. Once it got electrically charged, it got the ability to exert a force on the pieces of paper and attract them. This charge is called as static electricity.
