Question

A force of 200 N can produce a pressure of 20000 Pa. Calculate the area in cm² on which the force shall act to exert the pressure.

Answer 1

Step 1 Given data:

Force, $F=200N$

Pressure,$P=20,000Pa$
Step 2 Formula used:

$Area\left(A\right)=\frac{F}{P}$
Step 3 Finding area:

$$\begin{gathered} Area\left(A\right)=F/P \\ A=200/20000 \\ A=0.01m² \\ Toconvertm²tocm²,wemultiplytheareawith10000 \\ A=0.01\times 10000=100cm² \end{gathered}$$

Hence, the area in cm² on which the force shall act to exert the pressure of 20000 Pa, is $100c{m}^2$.
