Identify the pair of physical quantities which have different dimensions:
  1. Wave number and Rydberg's constant
  2. Stress and Coefficient of elasticity
  3. Coercivity and  Magnetisation
  4. Specific heat capacity and Latent heat

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.
