Match List I with List II. List-I (a) R_H (Rydberg constant) (b) h (Planck's constant) (c) μ_B (Magnetic field energy density) (d) η (coefficient of viscosity) List-II (i) kg m^-1 s^-1 (ii) kg m^2 s^-1 (iii) m^-1 (iv) kg m^-1 s^-2 Choose the most appropriate answer from the options given below: (1) (a) → (ii), (b) → (iii), (c) → (iv), (d) → (i) (2) (a) → (iii), (b) → (ii), (c) → (iv), (d) → (i) (3) (a) → (iv), (b) → (iii), (c) → (i), (d) → (ii) (4) (a) → (iii), (b) → (i), (c) → (ii), (d) → (iv)

  1. (a) → (ii), (b) → (iii), (c) → (iv), (d) → (i)
  2. (a) → (iii), (b) → (ii), (c) → (iv), (d) → (i)
  3. (a) → (iv), (b) → (iii), (c) → (i), (d) → (ii)
  4. (a) → (iii), (b) → (i), (c) → (ii), (d) → (iv)

Correct answer: (a) → (iii), (b) → (ii), (c) → (iv), (d) → (i)

Solution

The correct option matches the physical constants with their respective units: Rydberg constant (R_H) is expressed in m^-1, Planck's constant (h) in kg m^2 s^-1, magnetic field energy density (μ_B) in kg m^-1 s^-2, and the coefficient of viscosity (η) in kg m^-1 s^-1, accurately reflecting their definitions and dimensional analysis.
