If \( \mathrm{I}=50 \mathrm{~kg}-\mathrm{m}^{2} \), then how much torque will be applied to stop it in \( 10 \mathrm{sec} \). Its initial angular speed is 20 \( \mathrm{rad} / \mathrm{sec} \). :
(1) \( 100 \mathrm{~N}-\mathrm{m} \)
(2) \( 150 \mathrm{~N}-\mathrm{m} \)
(3) \( 200 \mathrm{~N}-\mathrm{m} \)
(4) \( 250 \mathrm{~N}-\mathrm{m} \)
