Kinematics Question 535
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/{{\sec }^{2}} $ ) [AIIMS 1987]
Options:
A) 4 m/sec
B)6.25 m/sec
C) 16 m/sec
D)None of the above
Show Answer
Answer:
Correct Answer: A
Solution:
Critical velocity at highest point$ =\sqrt{gR}=\sqrt{10\times 1.6} $ =4m/s
