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]
