Question:-
A plastic comb and a steel comb are rubbed in dry hair and brought near small pieces of paper.what will happen?
Answer:-
We rub a plastic comb with our dry hair and bring it near tiny pieces of paper. ... Actually, when we rub the plastic comb with our dry hair, the plastic comb gets electric charge due to friction. The electrically charged comb then exerts an electric force on the tiny pieces of paper and attracts them.
