Question

What is the force needed to produce a pressure of 1 pascal over a square area of side 2 m?

Answer 1

$$\begin{gathered} \mathrm{Given},\mathrm{pressure}=1\mathrm{Pa} \\ \mathrm{Area}\mathrm{of}\mathrm{square}=2\mathrm{m}\times 2\mathrm{m}=4{\mathrm{m}}^2 \\ \mathrm{Pressure}=\frac{\mathrm{Force}}{\mathrm{Area}}\Rightarrow \mathrm{Force}=\mathrm{Pressure}\times \mathrm{Area} \\ \mathrm{Therefore}, \\ \mathrm{Force}=1\times 4=4\mathrm{N} \end{gathered}$$
