Which of the following combinations of dimensions represents pressure?

  1. A
    \( [\text{M} \text{L}^{-1} \text{T}^{-2}] \)
  2. B
    \( [\text{M} \text{L} \text{T}^{-2}] \)
  3. C
    \( [\text{M} \text{L}^2 \text{T}^{-2}] \)
  4. D
    \( [\text{M} \text{L}^{-2} \text{T}^{-2}] \)
View Answer & Solution

Correct answer · Option A

\( [\text{M} \text{L}^{-1} \text{T}^{-2}] \)

Explanation

Pressure \( P = \frac{\text{Force}}{\text{Area}} = \frac{[\text{MLT}^{-2}]}{[\text{L}^2]} = [\text{ML}^{-1}\text{T}^{-2}] \).
