Match List I with List II.
$$\begin{array}{|l|l|l|l|}\hline & \text{List I} & & \text{List II} \\ \hline \text{A.} & \text{Angular momentum} & \text{I.} & [\text{ML}^2\text{T}^{-2}] \\ \hline \text{B.} & \text{Torque} & \text{II.} & [\text{ML}^{-2}\text{T}^{-2}] \\ \hline \text{C.} & \text{Stress} & \text{III.} & [\text{ML}^2\text{T}^{-1}] \\ \hline \text{D.} & \text{Pressure gradient} & \text{IV.} & [\text{ML}^{-1}\text{T}^{-2}] \\ \hline \end{array}$$
Choose the correct answer from the options given below:
Answer: (B) A-III, B-I, C-IV, D-II
- Angular momentum $=mvr$: $[\text{ML}^2\text{T}^{-1}]$ → III
- Torque $=Fr$: $[\text{ML}^2\text{T}^{-2}]$ → I
- Stress $=F/A$: $[\text{ML}^{-1}\text{T}^{-2}]$ → IV
- Pressure gradient $=P/L$: $[\text{ML}^{-2}\text{T}^{-2}]$ → II
