A bucket of water is being removled in vertical circle of radius 1m. Minimum frequency required to prevent the water from getting down the path is

A

`(20 pi)/(sqrt(10))`

B

`(2 pi)/(sqrt(5))`

C

`(sqrt(10))/(2pi)`

D

`(sqrt(5))/(2pi)`

Text Solution

Verified by Experts

The correct Answer is:
C
Minimum speed `v_("min")= r omega _("min")= r pi n_("min")`
`rArr ` Min imum frequency
`n_("min")=(V_("min"))/(pir) =(sqrt(10))/(2pi)`
