Question

Assertion: When we rub a comb in dry hair, then this comb attracts small pieces of paper.
Reason : The comb gets an electric charge that varies with the number of charged particles within the atoms present in the comb.

• A. Atoms are not divided
• B. Atoms are divisible
• C. Atoms repel each other
• D. Atoms can attract each other

Answer 1

The correct option is A

Atoms are not divided

An electrically charged object can attract an uncharged object. This means that on rubbing a 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.
