Q10JEE Main 2026 · 5 APR · SHIFT 2Difficult

Applications of Dimensional Analysis

Match List - I with List - II.

Figure

where h (Planck's constant), G (gravitational constant) and c (speed of light in vacuum) as

fundamental units.

Choose the correct answer from the options given below:

Show answer and solution

Answer: (b)

  1. Planck length =Ghc3= \sqrt{\frac{Gh}{c^{3}}}, so A-IV.
  2. Planck time =Ghc5= \sqrt{\frac{Gh}{c^{5}}}, so B-II.
  3. Planck mass =hcG= \sqrt{\frac{hc}{G}}, so C-I; the remaining temperature expression gives D-III.
  4. So the answer is (b) A-IV, B-II, C-I, D-III.
