The pair of physical quantities not having same dimensions is :

The pair of physical quantities not having same dimensions is :
  1. Pressure and Young's modulus
  2. Surface tension and impulse
  3. Torque and energy
  4. Angular momentum and Planck's constant

Solution

[Angular momentum $]=\mathrm{ML}^2 \mathrm{~T}^{-1}$
[Planck's Constant] $=\mathrm{ML}^2 \mathrm{~T}^{-1}$
[Torque] $=\mathrm{ML}^2 \mathrm{~T}^{-2}$
[Energy] $=\mathrm{ML}^2 \mathrm{~T}^{-2}$
[Surface tension] $=\mathrm{MT}^{-2}$
[Impulse]= MLT $^{-1}$
[Pressure $]=\mathrm{ML}^{-1} \mathrm{~T}^{-2}$
[Young's modulus] $=\mathrm{ML}^{-1} \mathrm{~T}^{-2}$
