JEE Main & Advanced Physics Two Dimensional Motion Question Bank Non-uniform Circular Motion

  • question_answer
    The angle turned by a body undergoing circular motion depends on time as \[\theta ={{\theta }_{0}}+{{\theta }_{1}}t+{{\theta }_{2}}{{t}^{2}}\]. Then the angular acceleration of the body is                                   [Orissa JEE 2005]

    A)             \[{{\theta }_{1}}\]     

    B)             \[{{\theta }_{2}}\]

    C)                         \[2{{\theta }_{1}}\]               

    D)                         \[2{{\theta }_{2}}\]            

    Correct Answer: D

    Solution :

                                Angular acceleration\[=\frac{{{d}^{2}}\theta }{d{{t}^{2}}}\]= 2q2
