Water is filled in a container upto height 3m. A small hole of area 'a' is punched in the wall of the container at a height 52.5 cm from the bottom. The cross sectional area of the container is A. If `a//A=0.1` then `v^2` is (where v is the velocity of water coming out of the hole)

A

`50`

B

`51`

C

`48`

D

`51.5`

Text Solution

Verified by Experts

The correct Answer is:
A
The square of the velocity of flux
`v^(2)=(2gh)/sqrt((1-((A_(0))/A)^(2)))`
`=(2xx10xx2.475)/sqrt(91-(0.1)^(2))=50m^(2)//s^(2)`
