A) \[2\pi a\]
B) a
C) \[\frac{a}{2\pi }\]
D) \[\frac{a}{\sqrt{2\pi }}\]
Correct Answer: D
Solution :
Rate of flow \[=\frac{d(Volume)}{dt}\,=Area\,\times \,\] (Velocity of flow) \[{{v}^{2}}=2gh\Rightarrow \,{{a}^{2}}\,\sqrt{2gh}\,=\pi {{r}^{2}}\sqrt{2g\mu x}\times 2\] \[\Rightarrow \,r=\frac{a}{\sqrt{2\pi }}\]
