A force of $60\text{ N}$ is applied uniformly over a flat surface area of $3\text{ m}^2$. What is the pressure exerted on the surface?
  1. $180\text{ N/m}^2$
  2. $20\text{ N/m}^2$
  3. $57\text{ N/m}^2$
  4. $63\text{ N/m}^2$

Solution

$\text{Pressure} = \frac{\text{Force}}{\text{Area}} = \frac{60\text{ N}}{3\text{ m}^2} = 20\text{ N/m}^2$.
