Identify the pair of physical quantities which have different dimensions:

Options

  1. AWave number and Rydberg's constant
  2. BStress and Coefficient of elasticity
  3. CCoercivity and Magnetisation
  4. DSpecific heat capacity and Latent heat

Correct answer

D. Specific heat capacity and Latent heat

Step-by-step solution

The SI unit of specific heat is J   kg - 1   K - 1 and the SI unit of latent heat is J   kg - 1 . We can see that the quantities in option D have different dimensions.
