0Centre of mass of a system is a unique point which is very helpful in solving the problems related to the motions of rigid bodies. In columns I and II, some statements regarding centre of mass are given. Match the columns:
\begin{tabular}{|c|l|c|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline (i) & \begin{tabular}{l}
In the absence of \\
external forces, the \\
internal forces
\end{tabular} & (a) & \begin{tabular}{l}
inside the \\
material of the \\
body
\end{tabular} \\
\hline (ii) & \begin{tabular}{l}
Centre of mass of a \\
body can be
\end{tabular} & (b) & \begin{tabular}{l}
the distribution \\
of its mass
\end{tabular} \\
\hline (iii) & \begin{tabular}{l}
The position of the \\
centre of mass of a \\
body depends on
\end{tabular} & (c) & \begin{tabular}{l}
do not affect the \\
motion the \\
centre of mass
\end{tabular} \\
\hline (iv) & \begin{tabular}{l}
Centre of mass of a \\
solid cylinder is
\end{tabular} & (d) & \begin{tabular}{l}
outside the of the \\
material of the \\
body
\end{tabular} \\
\hline
\end{tabular}
(1) i-a, d; ii - b, c; iii-c; iv - a
(2) i-c; ii-a; iii-b, c; iv-a, d
(3) i-a; ii-a, d; iii-b, c; iv - c
