A thin uniform bar of length \( \mathrm{L} \) and mass \( 8 \mathrm{~m} \) lies on a smooth horizontal table. Two point masses \( \mathrm{m} \) and \( 2 \mathrm{~m} \)
\( \mathrm{P} \)
moving in the same horizontal plane from opposite sides of the bar with speeds \( 2 v \) and \( v \) respectively. The
W
masses stick to the bar after collision at a distance and \( \frac{L}{3} \) and \( \frac{L}{6} \) respectively from the centre of the bar. If the bar starts rotating about its center of mass as a result of collision, the angular speed of the bar will be:
(1) \( \frac{v}{6 L} \)
(2) \( \frac{6 v}{5 L} \)
(3) \( \frac{3 v}{5 L} \)
(4) \( \frac{v}{5 L} \)
