Question

A person exerts the pressure of $48\mathrm{Pa}$ by applying a force of$24\mathrm{N}$on a box. Calculate the area over which the force is applied.

Answer 1

Step-1: Given data

Pressure= $\mathrm{P}=48\mathrm{Pa}$

Force=$\mathrm{F}=24\mathrm{N}$

Area=$\mathrm{A}=?$

Step-2: Formula used

Pressure=$\mathrm{P}=\frac{\mathrm{F}}{\mathrm{A}}$

Step-3: Calculating the area

Area=$\mathrm{A}=\frac{\mathrm{F}}{\mathrm{P}}=\frac{24}{48}=\frac{1}{2}=0.5{\mathrm{m}}^2$

Hence, the area of the box is $0.5{\mathrm{m}}^2$.
