Units & Dimensions

The pair of physical quantities not having the same dimensions is:

Show answer and solution

Answer: (c)

  1. Surface tension =F/l= F/l: MT−2\mathrm{MT^{-2}}; impulse =Ft= Ft: MLT−1\mathrm{MLT^{-1}}. Not the same.
  2. Angular momentum = hh (ML2T−1\mathrm{ML^2T^{-1}}), torque = energy (ML2T−2\mathrm{ML^2T^{-2}}), pressure = Young's modulus (ML−1T−2\mathrm{ML^{-1}T^{-2}}).
  3. So the answer is (c).
