Two particles $A$ and $B$ of equal mass $M$ are moving with the same speed $v$ as shown in figure. They collide completely inelastic and move as a single particle $C$. The angle $\theta$ that the path of $C$ makes with the $X$-axis is given by-\\
(1) $\tan \theta = \frac { \sqrt { 3 } - \sqrt { 2 } } { 1 - \sqrt { 2 } }$\\
(2) $\tan \theta = \frac { 1 - \sqrt { 2 } } { \sqrt { 2 } ( 1 + \sqrt { 3 } ) }$\\
(3) $\tan \theta = \frac { 1 - \sqrt { 3 } } { 1 + \sqrt { 2 } }$\\
(4) $\tan \theta = \frac { \sqrt { 3 } + \sqrt { 2 } } { 1 - \sqrt { 2 } }$
