Answer:
The correct answer is option 'b': 9.9 m/s
Explanation:
We know that for an ideal fluid the velocity of exit from a tank with the height of water 'h' is given by Torricelli's Law as
[tex]v=\sqrt{2gh}[/tex]
where,
'g' is acceleration due to gravity
'h' is the level of water
Applying the given values we obtain velocity as
[tex]v=\sqrt{2\times 9.81\times 5}=9.90m/s[/tex]
