Quick Answer: What happens when a positively charged comb attracts bits 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. … When the comb is brought close to paper an opposite charge is induced in the paper, and the opposite charges attract.

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.

What happen to the bits of paper place near the comb after using it why do you say so?

This is because the neutrality of polarity can be changed by electric field in this case. When you create – charge in the comb and you expose the pieces of paper to the electric field created by the charge, you will polarise them so that the part closer to the comb will be + and the other will be -.

What happens if you comb your hair and the comb becomes positively charged?

The material that gains electrons becomes negatively charged while the material losing electrons becomes positively charged. … If you comb your hair and the comb becomes positively charged, then your hair becomes negatively charged.

Is a comb positively or negatively charged?

When a comb is run through dry hair, the comb gets negatively charged due to friction. when the negatively charged comb is brought near a small bit of paper,the electron on the paper are repelled and positive charge will be nearer to the comb.

How does a charged comb attract bits 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 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 does a charged rod attracts paper?

H5UUvely Chusu If we take a positively charged glass rod near small pieces of paper, the rod attracts the pieces. … This is because the positively charged rod attracts the electrons of a paper piece towards itself. Some of the electrons accumulate at that edge of the paper piece which is closer to the rod.

Why do tiny bits of paper get attracted?

Tiny bots of paper undergo electrostatic force , when you rub a comb or pen or anything which is plastic. Therefore they get attracted to the thing which you have rubbed.

How Electric forces and electric fields interact in pieces of paper attracted by comb?

Explanation: When you rub the comb on your hair electric charges are accumulated on it, but the charge distribution is localized. This means that the electric field is non-uniform. This electric field polarizes the paper pieces and there are both positive and negative polarization charges.

What happens when hair gets positively charged?

It’s called ‘static electricity,’ and it happens when a few electrons get pulled off the atoms in your hair and onto your hat. That leaves your hair with not quite enough electrons. … Positive charges repel each other, so your charged hairs repel each other and stand out from your head.

Why does a comb become positively charged?

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.

When you brush your hair and scrape electrons from your hair the charge of your hair becomes?

And if electrons were scraped off the brush onto your hair, your hair would have a negative charge. In any charging process, no electrons are created or destroyed. Electrons are simply transferred from one material to another.

Are Combs positively charged?

The comb has become charged by friction, acquiring an excess of electrons. … This leaves a net positive charge on the side close to the comb, and since unlike charges attract, the paper is attracted to the comb.

What do you call the positively charged particles?

Protons are positively charged particles found within atomic nuclei. … Three quarks make up each proton — two “up” quarks (each with a two-thirds positive charge) and one “down” quark (with a one-third negative charge) — and they are held together by other subatomic particles called gluons, which are massless.

Which objects are attracted by a positively charged object?

Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.
