    A bucket tied at the end of a 1.6 m long string is whirled in a vertical circle with constant speed. What should be the minimum speed so that the water from the bucket does not spill, when the bucket is at the highest position (Take \[g=10m/{{\sec }^{2}}\])                               [AIIMS 1987]

    A)             4 m/sec

    B)                      6.25 m/sec

    C)             16 m/sec

    D)                      None of the above

    Correct Answer: A

    Solution :

                    Critical velocity at highest point\[=\sqrt{gR}=\sqrt{10\times 1.6}\]=4m/s
