Your question: Why does a comb run through dry hair attracts 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.

IMPORTANT:  What two factors determine the strength of coulombic attraction between particles in an atom?

When you run comb through dry hair it attracts bits of paper why what would you expect if the hair is wet or if it is a rainy day?

(a) This is because the comb gets charged by friction. The molecules in the paper gets polarised by the charged comb, resulting in a net force of attraction. If the hair is wet, or if it is rainy day, friction between hair and the comb reduces.

When a plastic comb is rubbed with dry hair it attracts small pieces of paper demonstrate this experiment?

ANSWER: 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.

Why does a comb run through dry hair attracts small bits?

When comb runs through dry hair, it attracts small bits of paper. 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.

Why is hair attracted to plastic comb during a hot day?

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.

Why does hair attract to a comb?

When a comb is run through your hair charges pass between your hair and the comb, so the comb becomes charged either positively or negatively, and the hair oppositely charged. When the comb is brought close to paper an opposite charge is induced in the paper, and the opposite charges attract.

Why does a plastic comb rubbed with dry hair attract 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.

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 plastic object such as a comb is run through dry hair the comb becomes charged and is able to attract tiny bits of paper this is known as which force?

By Definition, Static Electricity is the imbalance of electric charges on the surface or within a material. As we move a plastic comb through dry hair, the plastic comb gets polarized and hence static electricity is generated.

Does the attraction between the comb and the piece of papers last for longer period of time?

Does the attraction between the comb and the piece of papers last for longer period of time? 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 would the torn paper be more attractive to the comb than 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 do dry hair stand on when combined with a plastic comb?

When we run a comb on our dry hairs, then, the comb acquires an Electrostatic Positive Charge and our hairs acquires an Electrostatic Negative Charge due to which our dry hairs gets attracted towards the comb. The reason behind this attraction is– “Unlike charges attract each other.”

When you comb your hair with a plastic comb which object the hair or the comb holds on to its electrons more tightly What is the charge on this object?

hair is weaker at holding onto its electrons. So the hair would have a positive charge.

Why does plastic attract hair?

After being rubbed together, the plastic in the balloon picks up a negative charge, while the person’s hair ends up with a positive charge. … This attraction between oppositely charged objects is what we know as ‘static’.
