• # question_answer 44) A body of mass 10 kg and radius of gyration $0.1\text{ }m$is rotating about an axis. If angular speed is 10 rad/s, then angular momentum will be: A)  $1\,kg\,{{m}^{2}}/s$         B)  $0.1\,kg\,{{m}^{2}}/s$C)  $100\,\,kg\,{{m}^{2}}/s$       D)  $10\,\,kg\,{{m}^{2}}/s$

$J=I\omega =M{{K}^{2}}\omega =10\times {{(0.1)}^{2}}\times 10=1\,kg{{m}^{2}}{{s}^{-1}}$
