Question

A thrust of 20 N is acting on an area of 2 $m^2$. How much pressure is acting on the surface?

• A. $\text{10 N}{m}^{-2}$
• B. $\text{20 N}{m}^{-2}$
• C. $\text{5 N}{m}^{-2}$
• D. $\text{40 N}{m}^{-2}$

Answer 1

The correct option is A $\text{10 N}{m}^{-2}$

Pressure can be defined as the thrust acting per unit area.
Given, thrust $=20N$ and area $=2m^2$
Hence, Pressure = $\frac{Thrust}{Area}$ $=\frac{20}{2}$
$=10N{m}^{-2}$
