A cylinder contains a liquid upto a height 2.5 m . If now a small hole is made at bottom . Liquid comes out with a velocity

A

`5 m//s`

B

`6 m//s`

C

`7 m//s`

D

`2 m//s`

Text Solution

Verified by Experts

Velocity of efflux of the liquid
` = sqrt( 2 gh ) = sqrt( 2 xx 9.8 xx 2.5 ) = sqrt( 49 ) = 7 m//s `
