What happens when you rub hair scale?
A plastic scale after being rubbed against dry hair attracts bits of paper as it acquires a negative charge. The plastic scale gets electrically charged due to rubbing against dry hair. The plastic scale acquires charge due to static electricity.
When a ruler is rubbed in dry hair it attracts tiny bits of paper the force involved is?
Tiny bits of paper get attracted to a plastic comb or ruler which have been recently rubbed. We all know that this is due to electrostatic force.
What happens when a plastic scale rubbed with dry hair is brought near 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.
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 caused the paper bits to get attracted?
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.
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 ruler attract pieces of paper?
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 do tiny bits of paper get attracted when brought close to a plastic pen or comb which have recently been rubbed?
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.
