Question

The unit of Pressure is :
1. N/m²
2. N/m
3. J
4. J/s

Answer 1

Correct Answer - Option 1 : N/m²

CONCEPT:

• Force (F): The interaction which after applying on a body changes or try to change the state of rest or state of motion of a body is called force.
  • The SI unit of force is Newton (N)

Force (F) = Mass (m) × acceleration (a)

• Pressure (P): The force per unit area is called pressure.
• The SI unit of pressure is the pascal (Pa) or N/m2.
• The metric unit of pressure is the bar.

​EXPLANATION:

• The SI unit of pressure is the pascal or N/m². So option 1 is correct.
