Question

SI unit of thrust is ${\mathrm{Nm}}^{-2}$.

• A. True
• B. False

Answer 1

The correct option is B False

1. Thrust is the force acting normally on a surface.
2. The thrust exerted by an object placed on a surface is equivalent to its weight.
3. As it is a type of force, the S.I. unit of thrust is newton ($\mathrm{N}$).
4. Pressure is thrust per unit area.
5. The S.I. unit of pressure is ${\mathrm{Nm}}^{-2}$

Hence, the given statement is false.
