A bucket containing water is tied to one end of a rope of length 2.5 m and rotated about the other end in a vertical circle so that water does not spill even when bucet is upside down . What is the maximum velocity of the bucket at which this happens ? How many rotations per minute is it making `g = 10 m//s^(2) ` .
A
`2.5 m//s`
B
`4m//s`
C
`5m//s`
D
`7m//s`
Text Solution
Verified by Experts
The correct Answer is:
C
`V_(H ) = sqrt(rg ) = sqrt(2.5xx10)=5m//s`
