JEE Main 2022 · 24 Jun · Shift 1, Physics question 34

Identify the pair of physical quantities which have different dimensions :

Choose one option
Answer and worked solution

Official answer: D

Check each pair.

  • Wave number and Rydberg's constant: both L−1L^{-1}.
  • Stress and modulus of elasticity: both ML−1T−2ML^{-1}T^{-2}.
  • Coercivity and magnetisation: both A m−1^{-1}.
  • Specific heat (J kg−1^{-1}K−1^{-1}) and latent heat (J kg−1^{-1}): different, L2T−2K−1L^2T^{-2}K^{-1} against L2T−2L^2T^{-2}.

(D)
