Question

Which of the following pairs of physical quantities does not have same dimensional formula?

• A. Work and torque.
• B. Angular momentum and Planck's constant.
• C. Tension and surface tension.
• D. Impulse and linear momentum.

Answer 1

The correct option is C Tension and surface tension.

$\left[Tension\right]=\left[ML{T}^{-2}\right]$
$\left[SurfaceTension\right]=\frac{\left[ML{T}^{-2}\right]}{\left[L\right]}=\left[M{L}^0{T}^{-2}\right]$
