Physics · Units, Dimensions & Error Analysis
JEE Main 2026 — 4 April, Evening Shift — Question 1
Match LIST-I with LIST-II.
| LIST-I | LIST-II |
|---|---|
| A. Planck's constant | I. MLT⁻² |
| B. Stopping potential | II. T⁻¹ |
| C. Work function | III. MLT⁻¹ |
| D. Threshold frequency | IV. ML²T⁻³A⁻¹ |
- Option A:Correct
A-III, B-IV, C-I, D-II
- Option B:
A-I, B-II, C-III, D-IV
- Option C:
A-IV, B-III, C-I, D-II
- Option D:
A-I, B-IV, C-III, D-II
Answer: A
Step-by-step solution
[h]=ML²T⁻¹, stopping potential = ML²T⁻³A⁻¹, work function = ML²T⁻², threshold frequency = T⁻¹
