MCQ
Which of the following is dimensionally correct
  • A
    Pressure = Energy per unit area
  • Pressure = Energy per unit volume
  • C
    Pressure = Force per unit volume
  • D
    Pressure = Momentum per unit volume per unit time

Answer

Correct option: B.
Pressure = Energy per unit volume
b
(b) Pressure = $\frac{{{\rm{Force }}}}{{{\rm{Area}}}} = \frac{{{\rm{Energy}}}}{{{\rm{Volume}}}}$= $M{L^{ - 1}}{T^{ - 2}}$
