Show answer and solution
Correct option: A
Solution
Planck's constant h = E/f → [ML²T⁻²]/[T⁻¹] = [ML²T⁻¹] → A-III.
Stopping potential Vs is a voltage (energy per charge) → [ML²T⁻²]/[AT] = [ML²T⁻³A⁻¹] → B-IV.
Work function ø is energy → [ML²T⁻²] → C-I.
Momentum p = mv → [MLT⁻¹] → D-II.
This gives A-III, B-IV, C-I, D-II, which is option 1.
