CONCEPT

  • Dimensions: Dimensions of a physical quantity are the powers to which the fundamental units are raised to obtain one unit of that quantity.

CALCULATION:

The dimension of pressure is given as,

⇒ [P] = [M1 L-1 T-2]     -----(1)

  • The dimension of energy is given as,

⇒ [E] = [M1 L2 T-2]     -----(2)

  • The dimension of the area is given as,

⇒ [A] = [M0 L2 T]     -----(3)

  • The dimension of the volume is given as,

⇒ [V] = [M0 L3 T]     -----(4)

[Energy/Area] [Energy/Volume] [Energy×Area] [Energy×Volume]
[M1 L0 T-2] [M1 L-1 T-2] [M1 L4 T-2] [M1 L5 T-2]
  • From the above table, it is clear that the dimension of energy/volume is equal to the pressure.
  • Hence, option 2 is correct.
