Question

A $20\text{N}$ force is applied on an area of $2.5{\text{m}}^2$. Compute the pressure in $\text{Pa}$.

• A. 8

Answer 1

The correct option is A 8
Given:
Force, $\text{F}=20\text{N}$
Area of contact, $\text{A}=2.5{\text{m}}^2$

From definition of pressure $\left(\text{P}\right)$,
$\text{P}=\frac{\text{F}}{\text{A}}$
$\text{P}=\frac{20}{2.5}=\frac{40}{5}=8\text{Pa}$
