When a pressure measuring device is immersed in a liquid, a restoring force of 2 N is exerted by the spring. If the area of cross-section of the pistion is 10 `cm^(2)`, what pressure does the fluid exert on the piston?

Explanation

To find the pressure exerted by the fluid on the piston, we can use the formula for pressure:

\[ P = \frac{F}{A} \]

where:
- \( P \) is the pressure,
- \( F \) is the force exerted (in newtons),
- \( A \) is the area (in square meters).
