Question

Find the pressure, when a thrust of 20 N is applied on the surface area of 10 cm²?

Answer 1

Step 1: Given data,

Thrust = 20 N,

Surface area = 10 cm²

Step 2: Formula:

$Pressure=\frac{Thrust}{Area}$

Step 3: Calculation

Convert 10 cm² into m²

$10c{m}^2=10\times {\left({10}^{-2}\right)}^2{m}^2=10\times {10}^{-4}{m}^2$

substitute the values in the above formula

$Pressure=\frac{20}{10\times {10}^{-4}}=\frac{20}{{10}^{-3}}=20\times {10}^3$

Hence, the pressure is $20\times {10}^3\mathrm{Pascal}$
