Match List-(I) with List-(II).
$$\begin{array}{|l|l|l|l|}\hline & \text{List-(I)} & & \text{List-(II)} \\ \hline \text{a} & R_H\ \text{(Rydberg constant)} & \text{i} & \text{kg m}^{-1}\text{s}^{-1} \\ \hline \text{b} & h\ \text{(Planck's constant)} & \text{ii} & \text{kg m}^2\text{s}^{-1} \\ \hline \text{c} & \mu_B\ \text{(Magnetic field energy density)} & \text{iii} & \text{m}^{-1} \\ \hline \text{d} & \eta\ \text{(coefficient of viscosity)} & \text{iv} & \text{kg m}^{-1}\text{s}^{-2} \\ \hline \end{array}$$
Choose the most appropriate answer from the options given below:
Answer: (C) (a) − (iii), (b) − (ii), (c) − (iv), (d) − (i)
- Rydberg constant: $\dfrac{1}{\lambda} = R_H(\ldots)$, unit m$^{-1}$ (iii)
- Planck's constant: $E = h\nu$, unit J s $=$ kg m$^2$ s$^{-1}$ (ii)
- Energy density: J m$^{-3}$ $=$ kg m$^{-1}$ s$^{-2}$ (iv)
- Viscosity: Pa s $=$ kg m$^{-1}$ s$^{-1}$ (i)
