Question

what happens when a comb rub against here and is brought near the small pieces of paper?​

Answer 1

Answer:

When the comb is brought close to paper an opposite charge is induced in the paper, and the opposite charges attract. The charges move from one insulator to another on vigorous contact (i.e. by rubbing) to produce the two oppositely charged objects.

Answer 2

$\huge\mathtt\red{Answer}$

→Comb gets Charged due to Static Electricity.
→Similar to the positive and Negative charge ,there exist Neutral Charge.
→It is found that a charged object, whether positive or negative, may attract uncharged objects.
→This is because the comb gets charged when it is rubbed.
→This charge that is created when two objects are rubbed against each other is called static electricity.
