Match the LIST-I with LIST-II
$$\begin{array}{|l|l|l|l|}\hline & \text{List - I} & & \text{List - II} \\ \hline \text{A.} & \text{Planck's constant} & \text{I.} & \text{ML}^2\text{T}^{-2} \\ \hline \text{B.} & \text{Stopping potential} & \text{II.} & \text{T}^{-1} \\ \hline \text{C.} & \text{Work function} & \text{III.} & \text{ML}^2\text{T}^{-1} \\ \hline \text{D.} & \text{Threshold frequency} & \text{IV.} & \text{ML}^2\text{T}^{-3}\text{A}^{-1} \\ \hline \end{array}$$
Choose the correct answer from the options given below:
Answer: (A) A-III, B-IV, C-I, D-II
- Planck's constant: $h = E/\nu$ → $\text{ML}^2\text{T}^{-1}$ (III).
- Stopping potential is a voltage: $\dfrac{\text{energy}}{\text{charge}} = \dfrac{\text{ML}^2\text{T}^{-2}}{\text{AT}} = \text{ML}^2\text{T}^{-3}\text{A}^{-1}$ (IV).
- Work function is an energy: $\text{ML}^2\text{T}^{-2}$ (I).
- Threshold frequency: $\text{T}^{-1}$ (II).
