    A ball of mass 1 g and charge \[{{10}^{-8}}C\] moves from a point A. Where potential is 600 V to the point B where potential is zero. Velocity of the ball at the point B is 20 cm/s. The velocity of the ball at the point A will be

    A)  22.8 cm/s                           

    B)  228 cm/s            

    C)                         16.8 m/s             

    D)         168 m/s

    Correct Answer: A

    Solution :

    By using, \[\left( \frac{L}{R} \right)\] \[\because \] \[R=\frac{pV}{T}=\frac{[M{{L}^{-1}}{{T}^{-2}}][{{L}^{3}}]}{[\theta ]}\]
