Question

How much thrust will be required to exert a pressure of $20000Pa$ on an area of $1c{m}^2$?

• A. $1N$
• B. $100N$
• C. $2N$
• D. $200N$

Answer 1

The correct option is C $2N$

From definition of pressure,
$Pressure=\frac{Thrust}{Area}$
$Thrust=20000Pa\times 1c{m}^2$
$Thrust=20000Pa\times \frac{1}{{100}^2}{m}^2$
$Thrust=2N$
