Match **List - I** with **List - II**.
$$\begin{array}{|l|l|l|l|}\hline & \text{List - I} & & \text{List - II} \\ \hline \text{A.} & \text{Coefficient of viscosity} & \text{I.} & [ML^{-1}T^{-2}] \\ \hline \text{B.} & \text{Surface tension} & \text{II.} & [ML^{2}T^{-2}] \\ \hline \text{C.} & \text{Pressure} & \text{III.} & [ML^{0}T^{-2}] \\ \hline \text{D.} & \text{Surface energy} & \text{IV.} & [ML^{-1}T^{-1}] \\ \hline \end{array}$$
Choose the **correct** answer from the options given below :
Answer: (B) A-IV, B-III, C-I, D-II
- Viscosity: $\eta = \dfrac{F}{A\,(dv/dx)}$ → $[ML^{-1}T^{-1}]$ (IV)
- Surface tension: force/length → $[MT^{-2}] = [ML^0T^{-2}]$ (III)
- Pressure: force/area → $[ML^{-1}T^{-2}]$ (I)
- Surface energy (an energy) → $[ML^2T^{-2}]$ (II)
A-IV, B-III, C-I, D-II.
