Question

When a thrust of $20N$ is applied on a surface area of $10c{m}^2$, find the pressure.

Answer 1

Step 1. Given data

Thrust $=20N$

Area, $=10c{m}^2$ $=10\times {10}^{-4}{m}^2$

Step 2. Finding the pressure

We know that, pressure is given by, $Pressure=\frac{Thrust}{Area}$

Substituting the values into the formula

Pressure $=\frac{20}{10\times {10}^{-4}}$

$=2\times {10}^{4}Pa$

Hence, the pressure is $2\times {10}^{4}Pa$.
