  • question_answer A couple of \[{{10}^{5}}N-m\]is applied to a flywheel of mass 10 kg and radius of gyration 50m. Then the angular acceleration of the wheel is (in\[rad/{{s}^{2}}\])

    A)  200               

    B)  50

    C)  10                

    D)  4

    Correct Answer: D

    Solution :

    Angular acceleration is \[\alpha =\frac{\tau }{I}=\frac{\tau }{M{{K}^{2}}}=\frac{{{10}^{5}}}{10\times {{50}^{2}}}=4\frac{rad}{{{s}^{2}}}\]
