Two particles A and B, move with constant velocities $\displaystyle \overrightarrow{v_1}$ and $\displaystyle \overrightarrow{v_2}$. At the initial moment their position vectors are $\displaystyle \overrightarrow{r_1}$ and $\displaystyle \overrightarrow{r_2}$ respectively. The condition for particles A and B for their collision is :

$\displaystyle \frac{\vec{r}_1-\vec{r}_2}{\left|\vec{r}_1-\vec{r}_2\right|}=\frac{\vec{v}_2-\vec{v}_1}{\left|\vec{v}_2-\vec{v}_1\right|}$
