A) \[\sqrt{2gh}\]
B) \[\sqrt{2\left( gh+\frac{mg}{P\,A} \right)}\]
C) \[\sqrt{2\left( gh+\frac{mg}{A} \right)}\]
D) \[\sqrt{\left( 2gh+\frac{mg}{A} \right)}\]
Correct Answer: B
Solution :
Applying Bernoulli's theorem at 1 and 2 \[pgh+\frac{mg}{A}=\frac{1}{2}p{{\upsilon }^{2}}\] Neglect presence of atmosphere or, \[\upsilon =\sqrt{2\left( gh+\frac{mg}{{{P}_{A}}} \right)}\]You need to login to perform this action.
