Question

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

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

Answer 1

The correct option is B $10N{m}^{-2}$

Given:
Thrust = $20N$
Area = $2m^2$
Pressure is defined as the thrust acting per unit area.
$P=\frac{Thrust}{Area}=\frac{20}{2}=10N{m}^{-2}$
Hence, the pressure acting on the surface is $10N{m}^{-2}$.
