Can Combs attract paper?

Can Combs attract paper?

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.

What causes paper to stick 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.

Why is the comb initially unable to attract bits of paper but able to do so after being run through the boy’s hair consider the statements below and use one or more of them to give a correct explanation Check all that you will use in your?

Why is the comb initially unable to attract bits of paper, but able to do so after being run through the boy’s hair? Initially the paper is neutral. When the charged comb is held near the paper, the air becomes a good conductor and sparks are generated in the space between the comb and the paper.

Will the comb attract the paper if it is not rubbed with a piece of cloth first?

ANSWER: No. Your hair must become positively charged in order to repel a negative charge. If you bring a charged comb near tiny pieces of paper, the pieces will first be attracted to the comb, but after touching they will fly away.

Why does rubbing not get electrically charged easily?

(d) Copper/gold does not get electrically charged easily by rubbing.

How do you scale paper to attract?

If the same scale is rubbed with your hair and then if it is kept near paper pieces, it would start attracting them. This is because when a scale is rubbed against hair, static electricity is generated through it. Thus the scale gets charged and attracts the pieces of paper.

What happened to the pieces of paper when you place the comb above them?

When the paper touches the comb, some of the excess negative charge in the comb is transferred to the paper. Because their charges are like, the paper is then repelled. ANSWER: The paper is initially attracted to the comb because the comb causes separation of charge in the paper.

What happened to the bits of paper place near the comb?

6 Answers. 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 happened when you put the negatively charged comb to the slowly flowing or trickling water?

The comb attracts the stream of water in the same way. The charge on the comb attracts the molecules of water in the stream. Because the molecules in the stream can be moved easily, the stream bends toward the comb.

Why can charge only be transferred?

Polarization is the movement of electrons within a neutral object due to the electric field of a nearby charged object. It occurs without direct contact between the two objects. Electrons are transferred whenever there is friction between materials that differ in their ability to give up or accept electrons.

What Cannot be charged easily by friction?

Only non-conducting materials can be charged by friction, and copper is a conducting material. Hence, it can’t be charged by friction.

Why it is not safe to go out with an umbrella when there is heavy rain?

Answer: Heavy rain and thundering is accompanied by lightning. Lightning is basically the discharge of huge amount of electric charges from clouds towards the ground. Thus, it is not advisable and safe to go out with an umbrella when there is heavy rain, lightning or thunder.

Why does a plastic comb attract tiny bits of paper if?

because of electrostatic forces acting on it. when we rub the plastic comb it will either be charged negatively or positively. it will induce negative charges on the bits of paper if the comb is positively charged so, the bits of paper will be attracted by the plastic comb which is an insulator.

What happens when a comb is brought near a paper strip?

The same thing happens when the comb is brought near neutral paper strips. Within the papers strips, the electrons get either repelled or attracted according to whether the comb has a negative or a positive charge. This makes the paper strips have an unlike charge in the direction of the comb, and makes them rise towards it. Hope this Clears !!

How are electrons attracted to a paper comb?

Within the papers strips, the electrons get either repelled or attracted according to whether the comb has a negative or a positive charge. This makes the paper strips have an unlike charge in the direction of the comb, and makes them rise towards it.

What’s the difference between a comb and a paper?

If you thought casually about it, you probably assumed the comb had one charge on it and the paper had the opposite charge on it. But the paper is initially electrically neutral. It hasn’t any net charge, but it is attracted anyway.
