A person combs his hair on a dry day. The comb causes `10^(22)` electrons to leave the person's hair and stick to the comb. Calculate the charge the comb carries.

Text Solution

Verified by Experts

The correct Answer is:

`- 1.6xx10^(3) C`

Here, `n = 10^(22), e = 1.6xx10^(-19) = 1.6xx10^(3) C`
Due to excess of electrons, charge on the comb
`= - 1.6xx10^(3) C`

Geeta has dry hair. A comb ran through her dry hair attracts small bits of paper. She observes that Neeta with oily hair combs her hair, the combs could not attract small bits of paper. She consults her teacher for this and gets the answer. She then goes to the junior classes and shows this phenomenon as physics experiment to them. All the juniors feel very happy and tell her that they will also look for such interesting things in nature and try to find the answer. She succeeds in forming a science club in her school. Read the above passage and answer the following questions. (i) What according to you are the values displayed by Geeta? (ii) Explain the phenomenon involved.
