Q1.

Match List-I with List-II.

\[ \begin{array}{|clcl|} \hline & \text{List-I} & & \text{List-II} \\ \text{A.} & \text{Coefficient of viscosity} & \text{I.} & \left[ \mathrm{M L}^{-1} \mathrm{T}^{-1} \right] \\ \text{B.} & \text{Surface Tension} & \text{II.} & \left[ \mathrm{M T}^{-2} \right] \\ \text{C.} & \text{Angular momentum} & \text{III.} & \left[ \mathrm{M L}^2 \mathrm{T}^{-1} \right] \\ \text{D.} & \text{Rotational kinetic energy} & \text{IV.} & \left[ \mathrm{M L}^2 \mathrm{T}^{-2} \right] \\ \hline \end{array} \]

Q2.

All surfaces shown in the figure are assumed to be frictionless, and the pulleys and the string are light. The acceleration of the block of mass $2 \ \mathrm{kg}$ is:
