    In the above question 23, what is the change in its centripetal acceleration?

    A) \[\frac{{{\upsilon }^{2}}}{\pi r}\]                                 

    B) \[\frac{{{\upsilon }^{2}}}{r}\]

    C) \[\frac{2{{\upsilon }^{2}}}{\pi r}\]                   

    D)        \[\frac{2{{\upsilon }^{2}}}{r}\]

    Correct Answer: D

    Solution :

    [d] Change in acceleration \[=\frac{{{v}^{2}}}{r}-\left( -\frac{{{v}^{2}}}{r} \right)\] \[=\frac{2{{v}^{2}}}{r}\]
