Question

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/$se{c}^2$)

• A. 4 m/sec
• B. 6.25 m/sec
• C. 16 m/sec
• D. 8 m/sec

Answer 1

The correct option is A

4 m/sec

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