Answer» Two particles $A$ and $B$ moving in $x - y$ plane are at origin at $t = 0 sec$ . The initial velocity vectors of $A$ and $B$ are ${\to u}_{A} = 8^i m/s$ and ${\to u}_{B} = 8^j m/s$ . The acceleration of $A$ and $B$ are constant and are ${\to a}_{A} = - 2^i {m/s}^{2}$ and ${\to a}_{B} = - 2^j {m/s}^{2}$ . List-I gives certain statements regarding particle $A$ and $B$ . List - II gives corresponding results in SI units. Match the statements in List-I with corresponding results in List-II. $\begin{matrix} List-I & List-II (I) & The time (in seconds) at which velocity of A relative & (P) & 16 \sqrt{2} to B is zero (II) & The distance (in metres) between A and B when their & (Q) & 8 \sqrt{2} relative velocity is zero (III) & The magnitude of relative velocity of A and B at the & (R) & 8 instant they are at same position (S) & 4 \end{matrix}$
