    A ball of mass 0.25 kg attached to the end of a string of length 1.96 m is moving in a horizontal circle. The string will break if the tension is more than 25 N. What is the maximum speed with which the ball can be moved [CBSE PMT 1998]

    A)             14 m/s

    B)                      3 m/s

    C)             3.92 m/s

    D)                      5 m/s

    Correct Answer: A

    Solution :

                    \[T=\frac{m{{v}^{2}}}{r}\] Þ \[25=\frac{0.25\,\times {{v}^{2}}}{1.96}\] Þ \[v=14\,m/s\]
