Two particles each of mass \( m \) move in opposite direction along \( Y \)-axis. One
\( \mathrm{P} \) particle moves in positive direction with

W velocity \( v \) while the other particle moves in negative direction with speed \( 2 \mathrm{v} \). The total angular momentum of the system with respect to origin is
(1) Is zero
(2) Goes on increasing
(3) Goes on decreasing
(4) None of these
