  • question_answer
    A particle moves with constant speed v along a circular path of radius r and completes the circle in time T. The acceleration of the particle is                           [Orissa JEE 2002]

    A)             \[2\,\pi \,v/T\]

    B)                      \[2\,\pi \,r/T\]

    C)             \[2\,\pi \,{{r}^{2}}/T\]         

    D)             \[2\,\pi \,{{v}^{2}}/T\]

    Correct Answer: A

    Solution :

                    Acceleration\[={{\omega }^{2}}r=\frac{{{v}^{2}}}{r}=\omega v=\frac{2\pi }{T}v\]
