Question

Two bodies A and B (A is bigger than B) are rubbed together. Which of the following statements is true?

• A. A and B get equal and opposite charges
• B. A and B get equal and similar charges
• C. A gets more charge than B, but of opposite kind.
• D. A gets less charge than B, but of the opposite kind.

Answer 1

The correct option is A

A and B get equal and opposite charges

(A): A and B get equal and opposite charges

Explanation:

1. If any two substances in this list are rubbed against one another, the one higher in the order gets positively charged. And the other gets a negative charge.
2. Due to rubbing two bodies against each other electrons get transferred from one body to another.
3. Due to which in one body deficiency of electron will be there, due to which it will acquire a positive charge.
4. And the other will acquire a negative charge due to excess of the electron.
5. So both the body will get equal charge and of opposite nature.

Hence, the correct answer is an option (A): A and B get equal and opposite charges.
