Why does paper stick to the comb?

Why does paper stick to the comb?

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.

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

A comb is charged with static electricity by combing hair. In turn, the charged comb attracts pieces of paper. Thus, the attractive force on the paper molecules’ nuclei (which are closer) is stronger than the repulsive force on the paper molecule’s electrons (which are farther).

How do you make static electricity with a comb?

Here’s How: Comb vigorously! Comb everyone’s hair! On the vertical, bring the comb toward the water (but don’t touch the water) and the electricity you just generated with the plastic comb and your hair should cause the water to bend toward the comb. You may need to try it a couple of times to get it to work.

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 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.

Which experiment proves that static electric force is non contact force?

➡Take a comb rub it with ur hard and take small piece of paper and now move it near the comb u will see that the comb attarcts the papers this proves that electrostatic force is non contact force ……!!!!

What will happen when you rub your comb to your hair and bring it near to bits of paper?

Why does the comb attract the pieces of paper?

If you comb your hair on a dry day, the comb readily picks up small scraps of 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.

What happens when you rub a comb on 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.

Why does a comb get charged when it is rubbed?

This is because the comb gets charged when it is rubbed. All the objects that we see around us are made of atoms, which are small uncharged particles. It consists of a positive centre made of positively charged protons and neutral neutrons, and negatively charged electrons orbiting around it almost like planets orbit around the sun.

Can a neutral piece of paper be attracted to a capacitor?

A neutral piece of paper will not be attracted to either plate inside the parallel plates of a capacitor. The variation of the field is an essential part of the attraction mechanism.
