Speed of a particle moving in a circle of radius \( 2 \mathrm{~m} \) varies with time as \( v=2 t \) (SI units). At \( t=1 \mathrm{~s} \) match the following two columns:
\begin{tabular}{|l|l|c|c|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II (SI units) } \\
\hline (a) & \( \vec{a} \cdot \vec{v} \) & (p) & \( 2 \sqrt{2} \) \\
\hline (b) & \( |\vec{a} \times \vec{\omega}| \) & (q) & 2 \\
\hline (c) & \( \vec{v} \cdot \vec{\omega} \) & (r) & 4 \\
\hline (d) & \( |\vec{v} \times \vec{a}| \) & (s) & None \\
\hline
\end{tabular}

Here, symbols have their usual meanings.
(1) (a) \( \rightarrow \) (q) (b) \( \rightarrow \) (r) (c) \( \rightarrow \) (s) (d) \( \rightarrow \) (p)
(2) (a) \( \rightarrow \) (s) (b) \( \rightarrow \) (s) (c) \( \rightarrow \) (r) (d) \( \rightarrow \) (s)
(3) (a) \( \rightarrow \) (r) (b) \( \rightarrow \) (p) (c) \( \rightarrow \) (s) (d) \( \rightarrow \) (r)
(4) (a) \( \rightarrow \) (q) (b) \( \rightarrow \) (p) (c) \( \rightarrow \) (r) (d) \( \rightarrow \) (s)
