A cane filled with water is revolved in ...

A cane filled with water is revolved in a vertical circle of radius 4 m and water just does not fall down. The time period of revolution will be –

A

4 s

B

10 s

C

1 s

D

11 s

Text Solution

Verified by Experts

The correct Answer is:
A
Time period is given by
`=("Circumference" )/("Critical speed ")=(2pir)/(sqrt(gr))=(2xx22xx4)/(7xxsqrt(10xx4))=4 s`
