Best answer: How do you attract paper to a 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.

How can you explain a comb run through dry hair attracts pieces of paper?

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.

How do you make a comb magnet?


  1. Rip up the paper into tiny pieces.
  2. Run the comb through your hair a few times and move it over the small paper fragments.
  3. The paper jumps onto the comb.
  4. Comb your hair a few more times to recharge it’s “magnetic” ability.
  5. Place the ping pong ball on a flat surface and bring the comb close to it.

When we comb our dry hair the hair attracts to comb the force involved in this is?

When the comb runs through dry hair, it gets charged by friction. The molecules in the paper get polarized by the charged comb, resulting in a net force of attraction.

When a comb is rubbed on dry hair it can attract pieces of paper without touching them this is due to force?

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.

Can plastic comb attract paper?

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 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 does a comb run through dry hair attract small bits of paper what happens if the hair is wet?

This is because the comb gets charged by friction. Comb gets electrically charged by friction. Due to electric charge, paper gets polarized and it attracts small bits of paper. … But when the comb runs through wet hair no electric charge is produced because friction between hair and comb is reduced.

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 a plastic comb rubbed on dry hair attract pieces of paper?

Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper.

When a comb is run in dry hair it starts attracting small pieces of paper which after touching the comb often jump violently away from it why?

Now after the paper is touching the comb, the charge of comb is shared by the paper hence the comb as well as the paper have similar charge now. Since similar charges repel, so the piece of paper gets repelled now in the form of violent jump.
