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.
Why does a comb rubbed on hair attract pieces 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.
When you rub comb through dry hair it attracts small bits of paper Why?
When comb runs through dry hair, it attracts small bits of paper. This is because the comb gets charged by friction. Comb gets electrically charged by friction. Due to electric charge, paper gets polarized and it attracts small bits of paper.
When a comb is rubbed on dry hair it can attract pieces of paper without touching them this is due to <UNK>force?
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.
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.
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 we comb dry hair?
Complete step by step answer:irstly, when the comb is used to rub dry hair, it always acquires a negative charge or electron which the hair carries, where the comb is induced with the electron gotten from the hair then immediately the comb which is negatively charged comes in contact with the piece of paper which is …
Does the attraction between the comb and the piece of papers last for longer period of time?
Does the attraction between the comb and the piece of papers last for longer period of time? No, because the comb loses its net charge after some time. The exess charge of the comb transfers to earth through our body after some time.
When a plastic object such as a comb is run through dry hair the comb becomes charged and is able to attract tiny bits of paper this is known as which force?
By Definition, Static Electricity is the imbalance of electric charges on the surface or within a material. As we move a plastic comb through dry hair, the plastic comb gets polarized and hence static electricity is generated.
Why does a rubbed comb attract bits of paper 8?
Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper.
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.
