Explain why do bodies get electrified when they are rubbed together for a while?

Explanation

### Step-by-Step Text Solution:

1. **Understanding Atoms and Charges**:
- Every atom consists of protons and electrons. Protons carry a positive charge, while electrons carry a negative charge. In a neutral atom, the number of protons equals the number of electrons, resulting in no overall charge.

2. **Rubbing Bodies Together**:
- When two different bodies are rubbed together, friction occurs between their surfaces. This friction can cause electrons to be transferred from one body to another.
