Quick Answer: Why can not we attract pieces of paper with a comb after combing a wet hair?

Why Cannot we attract pieces of paper with a comb after combing wet hair?

The comb does not get charged and it will not attract small bits of paper.

Why does a comb rubbed on dry hair attract pieces of paper?

when plastic comb is rubbed with dry hair , it acquires charge due to static electricity and so it attracts pieces of paper which is uncharged.

Why is your hair attracted to a comb after combing your hair?

The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. This “separation of charge” is the reason for the collection of effects we call static electricity. If two objects have different charges, they attract (or pull towards) each other.

How does a comb attract paper?

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

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 do they fly away? SOLUTION: The paper is initially attracted to the comb because the comb causes separation of charge in the paper.

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).

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 comb is rubbed with dry hair both comb and paper get similarly charged?

Correct: A comb rubbed with hair and brought near pieces of r paper attracts them, because both have dissimilar charges.

What happens when a dry metal comb is rubbed through dry hair?

Answer: Explanation: Nothing will happen because metal comb will not charge while rubbing with dry hair as compared to plastic comb.

What happens when you rubbed the balloon on your hair?

Rubbing the balloon onto your hair or onto the wool fabric adds electrons to the balloon and causes the balloon to become negatively charged. … Your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it.

What happens to the pieces of paper when that come in contact with the ruler?

When the negatively charged ruler is brought near to the paper pieces, they are attracted to the ruler as the the electrons move around on the paper because of the large charge on the ruler. Electrons will move away from the ruler leaving a positive charge on the paper near the ruler, so they are attracted.

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’.
