    The tension in the string revolving in a vertical circle with a mass  \[m\] at the end which is at the lowest position [EAMCET (Engg.) 1995; AIIMS 2001]

    A)             \[\frac{m{{v}^{2}}}{r}\]

    B)                      \[\frac{m{{v}^{2}}}{r}-mg\]

    C)             \[\frac{m{{v}^{2}}}{r}+mg\]

    D)                      \[mg\]

    Correct Answer: C

    Solution :

                    Tension = Centrifugal force + weight \[=\frac{m{{v}^{2}}}{r}+mg\]
