State the Coulomb's Law. Write down its mathematical form.

Explanation

### Step-by-Step Solution:

1. **Understanding Coulomb's Law**:
- Coulomb's Law describes the interaction between two point charges. It states that the force experienced by each charge is dependent on the magnitude of the charges and the distance between them.

2. **Statement of Coulomb's Law**:
- The magnitude of the electric force (F) between two point charges (q1 and q2) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (r) between them.
