Question

The SI unit of pressure and thrust are respectively:

• A. Pa and N
• B. N and $N{m}^{-1}$
• C. N and Pa
• D. $N{m}^{-1}$ and N

Answer 1

The correct option is A

Pa and N

We know , Pressure $=\frac{Force}{Area}$

So, unit of pressure is $N{m}^{-2}$ which is called Pascal (Pa).
Since thrust is the perpendicular force acting on a body, its unit is Newton (N).
