Question

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

• A. Force
• B. Power
• C. Pressure
• D. Acceleration

Answer 1

The correct option is D Acceleration

$\frac{Energy}{Mass\times Length}$
$=\frac{\left[M{L}^2{T}^{-2}\right]}{\left[M\right]\left[L\right]}$
$=\left[L{T}^{-2}\right]$
This has the same dimension as acceleration.
