Bottom of a cylindrical vessel has a hole of area \(A\). If water is filled up to a height \(h\), it flows out in \(t\) seconds. If water is filled to a height \(4 h\), it will flow out in time
- A \(t\)
- B \(4 t\)
- C \(2 t\)
- D \(\frac{t}{4}\)
Answer & Solution
Correct Answer
(C) \(2 t\)
Step-by-step Solution
Detailed explanation
\[ \text { The given situation is shown in the figure, } \] Time taken to flow out of water upto height \(h\) from hole completely, \[ t=\sqrt{\frac{2 h}{g}} \] When, \(\quad h^{\prime}=4 h\), then…
