When a comb is run through your hair charges pass between your hair and the comb, so the comb becomes charged either positively or negatively, and the hair oppositely charged. When the comb is brought close to paper an opposite charge is induced in the paper, and the opposite charges attract.
Why does hair stand up after combing?
When your hair is dry, especially after washing it and using a hair dryer, the various strands of hair may stick up and spread apart when you try to comb it. The reason is because the dry hair tends to collect positive (+) electrical charges when combed with a plastic comb.
Why does a comb rubbed on hair attract pieces of paper?
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 is a comb negatively charged?
The molecules orientate their dipoles, the negative oxygen towards the comb; the positively charged hydrogens away from it. When you comb your hair with a nylon comb, both the comb and your hair become charged. … This is a result of your hairs repelling each other because they are charged.
Can combing hair cause a spark?
Well, a comb isn’t a point charge. … The voltage required to zap you with static electricity when you touch a doorknob is a surprisingly high number on the order of 10,000 volts, so we’ll say the comb is charged to that potential since a comb can hold enough charge to produce a spark.
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 if you comb your hair and the comb becomes positively charged?
The material that gains electrons becomes negatively charged while the material losing electrons becomes positively charged. … If you comb your hair and the comb becomes positively charged, then your hair becomes negatively charged.
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.
When you rub a comb with your 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 …
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 do you think comb attracts some of your hair strands and papers Why do you think balloon attracts hair strands?
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 …
What about bringing the two rubbed balloons near each other?
Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.
What happens when you put a comb near water?
The answer is static electricity. Static electricity often happens when you rub things together. Combing your hair creates static electricity. … When the negatively charged comb comes near the water, it repels the electrons in the water, so that the side of the water nearest the comb then has a positive charge.
Why does hair become electrified?
So, What Causes Hair Static? Static electricity is created when two unlike objects rub against each other. … When the material of your hat rubs against the strands of your hair, they swap electrons. This swap causes a kind of electric charge to build up on your hair.
Can static in hair 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. … These tricks can double up as a hair loss solution as they provide effective hair treatment and make them stronger and long-lasting.
Why is hair static?
What causes static 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. … Plus, the elements, a lack of moisture in the air, and heated indoor environments can all exacerbate static hair.
