Match List I with List II List-I (A) Planck's constant (h) (B) Stopping potential (Vs) (C) Work function (ϕ) (D) Momentum (p) List-II (I) [M^1 L^2 T^-2] (II) [M^1 L^1 T^-1] (III) [M^1 L^2 T^-1] (IV) [M^1 L^2 T^-3 A^-1] Choose the correct answer from the options given below:

1. A-II, B-IV, C-I, D-II
2. A-I, B-III, C-IV, D-II
3. A-II, B-IV, C-III, D-I
4. A-III, B-I, C-II, D-IV

Correct answer: A-I, B-III, C-IV, D-II

Solution

The correct matches align the physical quantities with their respective dimensional formulas: Planck's constant (h) has dimensions of energy multiplied by time, which corresponds to [M^1 L^2 T^-2]; stopping potential (Vs) relates to energy per charge, matching [M^1 L^2 T^-3 A^-1]; work function (ϕ) is energy, thus [M^1 L^2 T^-2]; and momentum (p) is mass times velocity, fitting [M^1 L^1 T^-1].
