A particle of mass \( 1 \mathrm{~kg} \) is projected with velocity
\( \mathrm{P} \)
\( 20 \sqrt{2} \mathrm{~m} / \mathrm{s} \) at \( 45^{\circ} \) with ground. When, the particle is at highest point \( \left(g=10 \mathrm{~m} / \mathrm{s}^{2}\right) \)
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{3}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline (A) & \begin{tabular}{l}
Net torque on the \\
particle about point of \\
projection
\end{tabular} & (P) & 200 SI unit \\
\hline (B) & \begin{tabular}{l}
Angular momentum of \\
the particle about point \\
of projection
\end{tabular} & (Q) & 400 SI unit \\
\hline (C) & \begin{tabular}{l}
Velocity at the highest \\
point
