Match List I with List II List-I A. Spring constant B. Angular speed C. Angular momentum D. Moment of Inertia List-II I. [T^-1] II. [MT^-2] III. [ML^2] IV. [ML^2T^-1] Choose the correct answer from the options given below:

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

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

Solution

The correct matches reflect the dimensional analysis of each physical quantity: the spring constant (A) has dimensions of force per unit displacement, which is [MT^-2]; angular speed (B) is the rate of rotation, measured in radians per second, giving it dimensions of [T^-1]; angular momentum (C) is the product of moment of inertia and angular velocity, resulting in dimensions of [ML^2T^-1]; and moment of inertia (D) is mass times the square of distance, leading to dimensions of [ML^2].
