Question: Why does the ruler rubbed on hair attract paper pieces?

When a ruler is rubbed in dry hair it attracts tiny bits of paper the force involved is?

When the comb is rubbed with dry hair, then it gets electric charge. This electrically charged because comb exerts an electric force on the tiny pieces of paper and attracts them.

When a comb rubbed with dry hair attracts pieces of paper this is because?

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.

When a plastic comb is rubbed in dry hair it attracts tiny pieces of paper which force is involved in this process?

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 do tiny bits of paper get attracted when brought close to a balloon?

When you bring the balloon near a little piece of paper, the negative balloon repels the electrons in the paper so part of the paper near the balloon is positive. Since positive and negative attract, the paper moves toward the balloon. The negatively charged balloon attracts the paper.

What happens to the pieces of paper when that come in contact with the ruler?

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.

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.

What happens when a dry metal comb is rubbed through dry hair?

Answer: Explanation: Nothing will happen because metal comb will not charge while rubbing with dry hair as compared to plastic comb.

How can a comb attract small 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.

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

Q2) Why does a plastic comb rubbed with dry hair attract bits of paper ? Solution: A plastic comb rubbed with dry hair generates charges and attracts bits of paper.

When a comb is rubbed against hair force generated in it is?

This is because the comb gets charged when it is rubbed. This charge that is created when two objects are rubbed against each other is called static electricity.
