The unit of pressure is
- Akg / cm²
- Bkg / cm
- Ckg / mm
- Dkg / cm³
- ENone of the above / More than one of the above
Show answer and explanation
Correct answer: (e) None of the above / More than one of the above
Explanation
Pressure is force per unit area, P = F/A; its SI unit is the pascal (Pa) = N/m².
In MKS terms this equals kg·m⁻¹·s⁻²; the CGS unit is the barye.
None of kg/cm², kg/cm, kg/mm or kg/cm³ is a correct SI unit of pressure.
