Choose the most appropriate answer from the options given below :
| List - I | List - II | ||
|---|---|---|---|
| (a) | $${R_H}$$ (Rydberg constant) | (i) | $$kg\,{m^{ - 1}}{s^{ - 1}}$$ |
| (b) | h (Planck's constant) | (ii) | $$kg\,{m^2}{s^{ - 1}}$$ |
| (c) | $${\mu _B}$$ (Magnetic field energy density) | (iii) | $$\,{m^{ - 1}}$$ |
| (d) | $$\eta $$ (coefficient of viscocity) | (iv) | $$kg\,{m^{ - 1}}{s^{ - 2}}$$ |
Choose the most appropriate answer from the options given below :
(a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
