#### Identify the pair of physical quantities which have different dimensions:Option: 1 Wave number and Rydberg's constantOption: 2 Stress and Coefficient of elasticityOption: 3  Coercivity and MagnetisationOption: 4 Specific heat capacity and Latent heat

SI unit of :
Specific heat capacity : $\mathrm{\frac{J}{kg\: K}}$

Latent heat : $\mathrm{\frac{J}{kg}}$
$\therefore$  Specific heat capacity and Latent heat has different dimensions

The correct option is (4)
