Best answer: What type of electricity makes hair 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.

Which type of force causes the paper to stick to the comb?

Electrostatic force is the force between two point charges . When we rubbed any rod or comp with hair due to friction heat is produced and comb lose its electron and get positively charged. when we bring comb near to the piece of paper due to induction paper also get negative charge and attract the comb.

Is hair positively or negatively charged?

Untreated human hair has a strongly negative surface charge.

Which force can cause your hair to attract to a comb?

Hair Static

Because opposites polarities form an attractive force and charges of the same polarity form a repulsive force, the hair will be attracted strongly to the comb.

How does electricity affect hair?

Static hair occurs when your hair builds up an electric charge, meaning it has gained some extra electrons thanks to friction or a change in humidity. That makes the strands of your hair repel each other, leaving your hair frizzy and difficult to style.

Does electricity cause hair loss?

Static hair occurs when static electricity builds up in the hair strands, causing them to repel each other. This leads to frizzy hair and, in extreme cases, can even cause hair loss.

Can you lift the bits of paper with the plastic comb?

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. Initially the comb is electrically neutral. So it has no effect on the tiny pieces of paper.

Why does paper attract to a comb?

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.

What type of material Cannot be charged?

Both the rods and the duster are made of insulating materials. Insulators prevent the electrons from moving and the charge remains static . Conductors , on the other hand, cannot become charged, as the electrons can move through them.

What is hair attracted to?

A basic law is that similar charges (positive to positive) repel each other, and opposite charges (negative to positive) attract each other. Your positively charged hair gets attracted to the negatively charged hat.

Why does hair stand on end with static electricity?

The rubbing of certain materials against one another can transfer negative charges, or electrons. … Remember, objects with the same charge repel each other. Because they have the same charge, your hair will stand on end. Your hairs are simply trying to get as far away from each other as possible!

Are humans positively charged?

Electricity is everywhere, even in the human body. Our cells are specialized to conduct electrical currents. … Resting cells are negatively charged on the inside, while the outside environment is more positively charged. This is due to a slight imbalance between positive and negative ions inside and outside the cell.
