When two bodies are rubbed against each other?

Options

A. They acquire equal and similar charges.
B. They acquire equal and opposite charges.
C. They acquire unequal and similar charges.
D. They acquire unequal and opposite charges.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Process of Rubbing:** When two bodies are rubbed against each other, they interact through friction. This friction causes the transfer of electrons from one body to another.

2. **Electron Transfer:** One of the bodies loses electrons, which results in a positive charge, while the other body gains those electrons, resulting in a negative charge. This transfer occurs because of the difference in the materials of the two bodies.

3. **Charge Acquisition:** After rubbing, one body will have a surplus of positive charge (due to the loss of electrons), and the other body will have a surplus of negative charge (due to the gain of electrons).

4. **Magnitude of Charges:** The amount of charge acquired by both bodies is equal in magnitude but opposite in nature. This means that if one body has a charge of +Q, the other will have a charge of -Q.

5. **Conclusion:** Therefore, when two bodies are rubbed against each other, they acquire unequal and opposite charges. The correct answer is option 2: they acquire equal and opposite charge.
