Match List I with List II.
List-IList-II
(A) Planck's constant (h)(I) [M¹L²T⁻²]
(B) Stopping potential (Vₛ)(II) [M¹L¹T⁻¹]
(C) Work function (φ)(III) [M¹L²T⁻¹]
(D) Momentum (p)(IV) [M¹L²T⁻³A⁻¹]

Choose the correct answer from the options given below:

Asked in JEE Main 24th Jan 1st Shift 2023 · Matching quantities to their dimensions

Answer: (2) (A) → (III), (B) → (IV), (C) → (I), (D) → (II)

Step-by-step solution

A: Planck's constant is [ML²T⁻¹], so (III).

B: the stopping potential is a voltage, [ML²T⁻³A⁻¹], so (IV).

C: the work function is an energy, [ML²T⁻²], so (I).

D: momentum is [MLT⁻¹], so (II).

Hence A-III, B-IV, C-I, D-II.
