Question

1 $Pa$ is equal to

• A. $1N/m^2$
• B. $10N/m^2$
• C. $100N/m^2$
• D. $100000N/m^2$

Answer 1

The correct option is A

$1N/m^2$

1. From the definition of pressure, it is the force applied per unit area.
2. The SI unit of pressure $N/m^2$ is also known as Pascal ($Pa$).
3. $1Pa$ is the pressure exerted by $1newtonforce$ on $1mete{r}^{2}area$.
4. Thus, $1Pa=1N/m^2$.

Hence Option(A) is correct.
