Answer
The correct formula for pressure is \( P = \frac{F}{A} \).
Solution
The correct formula for pressure (\( P \)) is:
\[ P = \frac{F}{A} \]
Where:
- \( F \) is the force applied.
- \( A \) is the area over which the force is distributed.
**Answer:**
**c. \( P = \frac{F}{A} \)**

Explain 
Simplify this solution The Deep Dive
The correct formula for pressure is \( P=F / A \), which means pressure (P) equals the force (F) applied per unit area (A). It demonstrates that as the area over which a force is distributed increases, the pressure exerted decreases. This principle is why a sharp knife cuts better than a dull one—it's all about the pressure! In real-world applications, pressure is crucial in various fields, from engineering to meteorology. For instance, in hydraulics, a small force applied over a small area can generate a much larger force over a larger area, allowing heavy machinery to operate smoothly. Similarly, air pressure affects weather patterns, influencing storms and temperature.
