A fan of moment of inertia \( 0.6 \mathrm{kgm}^{2} \) is to run upto a working speed of \( 0.5 \) revolution per second. Indicate the correct value of the angular momentum of the fan
(1) \( 0.6 \pi \mathrm{kg} \times \frac{\text { metre }^{2}}{\mathrm{sec}} \)
(2) \( 6 \pi \mathrm{kg} \times \frac{\text { metre }^{2}}{\mathrm{sec}} \)
(3) \( 3 \pi \mathrm{kg} \times \frac{\text { metre }^{2}}{\mathrm{sec}} \)
(4) \( \frac{\pi}{6} \mathrm{~kg} \times \frac{\text { metre }^{2}}{\mathrm{sec}} \)
\( \mathrm{P} \)
