Question

The physical quantity which has dimensional formula as that of $\frac{\text{Energy}}{\text{Mass} \times \text{Length}}$ is

• A. (a) Force
• A. (b) Power
• A. (c) Pressure
• A. (d) Acceleration

Answer 1

(d)

Sol. $\frac{\text{Energy}}{\text{mass} \times \text{length}} = \frac{\lbrack ML^{2}T^{- 2}\rbrack}{\lbrack M\rbrack\lbrack L\rbrack} = \lbrack LT^{- 2}\rbrack$
