What is the unit of pressure?
- ANewton / sq. meter
- BNewton-meter
- CNewton
- DNewton/meter
- ENone of the above/More than one of the above
Show answer and explanation
Correct answer: (a) Newton / sq. meter
Explanation
Pressure is force per unit area, so its SI unit is the newton per square metre (N/m²), called the pascal (Pa).
The newton-metre is the unit of work (or torque), and the newton the unit of force.
