A cylinder of height 20 m is completely filled with water. The velocity of efflux of water (in `ms^(-1)`) through a small hole on the side of the cylinder near its bottom is: `[g=10m//s^(2)]`

A

10 m/s

B

20 m/s

C

40 m/s

D

5 m/s

Text Solution

Verified by Experts

The correct Answer is:
B

Velocity of effux
`b=sqrt(2gh)`
`=sqrt(2xx10xx20)=sqrt(400)`
`=20m//s`
