JEE Main 2024 — 27 January, Shift 1 — Question 44

Given below are two statements : one is labelled as Statement I and the other is labelled as Statement II:

Statement I: Planck's constant and angular momentum have same dimensions.

Statement II: Linear momentum and moment of force have same dimensions.

In the light of the above statements, choose the correct answer from the options given below :

  1. Option A:

    Statement I is true but Statement II is false

    Correct
  2. Option B:

    Both Statement I and Statement II are false

  3. Option C:

    Both Statement I and Statement II are true

  4. Option D:

    Statement I is false but Statement II is true

Answer: A

Step-by-step solution

[h]=ML2 T−1[\mathrm{h}]=\mathrm{ML}^{2} \mathrm{~T}^{-1}

[L]=ML2 T−1[\mathrm{L}]=\mathrm{ML}^{2} \mathrm{~T}^{-1}

[P]=MLT−1[\mathrm{P}]=\mathrm{MLT}^{-1}

[τ]=ML2 T−2[\tau]=\mathrm{ML}^{2} \mathrm{~T}^{-2} (

Here h is Planck's constant, L is angular momentum, P is linear momentum and τ\tau is moment of force)
