A circular disc of mass \( 4 \mathrm{~kg} \) and of radius
\( \mathrm{P} \) \( 10 \mathrm{~cm} \) is rotating about its natural axis at the

W rate of \( 5 \mathrm{rad} / \mathrm{sec} \). Its angular momentum is
(1) \( 0.25 \mathrm{kgm}^{2} \mathrm{~s}^{-1} \)
(2) \( 0.1 \mathrm{kgm}^{2} \mathrm{~s}^{-1} \)
(3) \( 2.5 \mathrm{kgm}^{2} \mathrm{~s}^{-1} \)
(4) \( 0.2 \mathrm{kgm}^{2} \mathrm{~s}^{-1} \)
