Question

Q) Give the scientific reasons

1) small bits of paper are attracted by aplactic comb which has been move vigorously through dry hair?​

Answer 1

Answer:

When we rub our hairs with a comb, and then try to attract small pieces of paper, they're attracted by the comb. The pieces of the paper were not electrified before they were attracted. Then they might be neutral. Why does the comb attract the pieces of the paper if they're neutral, and have no influence of a specific charge on them (Pieces of paper).This is because the neutrality of polarity can be changed by electric field in this case. When you create - charge in the comb and you expose the pieces of paper to the electric field created by the charge, you will polarise them so that the part closer to the comb will be + and the other will be- .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 paper gets attracted...

Answer 2

Answer:

yes

Explanation:

Initially the comb is electricity neutral.So it has no effect on the tiny pieces of paper when the comb is rubbed on a dry cloth,it's gets electrically charged an electric force on the tiny pieces of paper and attracts them.
