Question
What is the unit of pressure in an S.I system?
- N - m
- N - m2
Hint:
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
The correct answer is:
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
SI unit of force is Newton(N). SI unit of area is m2.
SI unit of pressure is N/m2
