JEE Main 2025 · 29 January · Morning Shift · Physics · Units and Dimensions

The pair of physical quantities not having same dimensions is :

The pair of physical quantities not having same dimensions is :

Options

  1. APressure and Young's modulus
  2. BSurface tension and impulse
  3. CTorque and energy
  4. DAngular momentum and Planck's constant

Correct answer

B. Surface tension and impulse

Step-by-step solution

[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}
