Basically, when an electrification takes place, electrons are not created but they are transferred….. in the case of comb attracting tiny tiny bits of papers when rubbed with dry hair is because electrons from the dry hair gets transferred to the comb and now the comb induces a dipole in the bitties of paper and the …
Does a metal rubbed hair attract pieces of paper?
with plastic scale it is possible, because rubbing it with your hair generates static electricity – as plastic is a bad conductor of electricity. where as metal scale absorbs electrons and hence it doesn’t generate that effect. Bits of paper are dielectric and get attracted through dielectrophoretic force.
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 a comb is rubbed with dry hair it attracts small bits of paper give reason?
Plastic comb gets electrically charged due to rubbing & therefore it attracts tiny pieces of paper. A charged body can attract an uncharged body.
Does the attraction between the rubbed comb and the pieces of papers last long Why?
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.
Do you think a metallic aluminum comb can attract the pieces of paper?
ANSWER: The paper is initially attracted to the comb because the comb causes separation of charge in the paper. The part of the paper pieces with positive charge is attracted to the comb.
Why do tiny bits of paper get attracted?
Tiny bots of paper undergo electrostatic force , when you rub a comb or pen or anything which is plastic. Therefore they get attracted to the thing which you have rubbed.
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.
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.
Why does a plastic comb rubbed with dry hair attracts tiny pieces of paper class 8?
When a plastic comb is dry hair, it becomes negatively charged. The negatively charged comb induces a positive charge on the pieces of paper which are neutral in nature. As we know that the unlike charges attract each other, plastic comb attracts tiny pieces of paper.
Which of the following thing when rubbed with dry hair does not attract small 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.
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.
Which force is involved when a plastic comb rubbed in dry hair picking up tiny pieces of paper?
Answer: A plastic comb when rubbed with hair gets electrically charged and can attract small pieces of paper. This is due to the presence of electrostatic forces. … This happens because by rubbing charge get formed on the comb.
What happens to your hair after rubbing the comb balloon on it repeatedly how about the tissue paper?
When a rubber balloon is rubbed against human hair, electrons are transferred from the hair to the rubber, giving the balloon a net negative charge, and leaving the hair with a net positive charge.
Why is hair attracted to comb during a hot day?
The comb, covered in negatively charged electrons, becomes negatively charged as well, and your hair is left with a positive charge. … If two objects have different charges, they attract (or pull towards) each other.
Which force is responsible for the attraction between a tiny bits of paper and a recently rubbed plastic comb?
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.
