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 ........ $m/sec$ (Take $g = 10\,m/{\sec ^2}$)

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