Question

The SI units of thrust and pressure are respectively given by :

• A. $N$, $N{m}^2$
• B. $N$, $N{m}^{-2}$
• C. $N{m}^{-1}$, $N{m}^{-2}$
• D. $N{m}^{-2}$, $N$

Answer 1

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

The SI unit of thurst is same as that of Force that is $N$

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

SI unit of Force is $N$

SI unit of Area is $m^2$

Hence unit of Pressure is $\frac{N}{m^2}$
