Question

If we rub a plastic comb on dry hair for some time and bring this comb near small pieces of paper, it attracts small pieces of paper. Which of the following can be related to this?

• A. Atoms are indivisible
• B. Atoms are divisible
• C. Atoms repel each other
• D. Atoms can attract each other

Answer 1

The correct option is B

Atoms are divisible

An electrically charged object can attract an uncharged object. This means that on rubbing a plastic comb with dry hair, the comb gets an electric charge, this electric charge rises due to an increase or decrease in the number of charged particles within the atoms present in the comb. So, we can say that some charged particles are present in the atoms of the matter which can be removed. Thus, atoms are divisible.
