The pair of physical quantities not having same dimensions is :

Show answer and solution

Answer: (B) Surface tension and impulse

[Angular momentum ]=ML2 T−1]=\mathrm{ML}^2 \mathrm{~T}^{-1}
[Planck's Constant] =ML2 T−1=\mathrm{ML}^2 \mathrm{~T}^{-1}
[Torque] =ML2 T−2=\mathrm{ML}^2 \mathrm{~T}^{-2}
[Energy] =ML2 T−2=\mathrm{ML}^2 \mathrm{~T}^{-2}
[Surface tension] =MT−2=\mathrm{MT}^{-2}
[Impulse]= MLT −1^{-1}
[Pressure ]=ML−1 T−2]=\mathrm{ML}^{-1} \mathrm{~T}^{-2}
[Young's modulus] =ML−1 T−2=\mathrm{ML}^{-1} \mathrm{~T}^{-2}
