Choose the correct answer from the options given below:

Show answer and solution

Answer: (c)

  1. Spring constant =F/x=[MT−2]= F/x = [\mathrm{MT^{-2}}] → II.
  2. Angular speed =θ/t=[T−1]= \theta/t = [\mathrm{T^{-1}}] → I.
  3. Angular momentum =Iω=[ML2T−1]= I\omega = [\mathrm{ML^2T^{-1}}] → IV.
  4. Moment of inertia =mr2=[ML2]= mr^2 = [\mathrm{ML^2}] → III.
  5. So the answer is (c) A-II, B-I, C-IV, D-III.
