Question

Water is filled in a container up to height $3m$. A small hole of area $a$ is punched in the wall of the container at a height $52.5cm$ from the bottom. The cross sectional area of the container is $A$. If $a/A=0$; then $v^2$ is (where $v$ is the velocity of water coming out of the hole)

• A. $50$
• B. $51$
• C. $48$
• D. $51.5$

Answer 1

The correct option is A $50$

Given $\frac{a}{A}=0\Rightarrow V_x=\sqrt{2gH}{V}^2=2gH=2\times 10\times 2.5=50$
