A water barrel having water upto a depth \(d\) is placed on a table of height \(h\). A small hole is made on the wall of the barrel at its bottom. If the stream of water coming out of the hole falls on the ground at a horizontal distance \(R\) from the barrel, then the value of \(d\) is
- A \(\frac{4 h}{R^2}\)
- B \(4 h R^2\)
- C \(\frac{R^2}{4 h}\)
- D \(\frac{h}{4 R^2}\)
Answer & Solution
Correct Answer
(C) \(\frac{R^2}{4 h}\)
Step-by-step Solution
Detailed explanation
Velocity of efflux of liquid \(v=\sqrt{2 g d}\) Vertical height fall by the liquid \(=h\) \(\therefore\) Time taken by the liquid \(t=\frac{\sqrt{2 h}}{g}\) \(\therefore\) Horizontal range \(=\) velocity \(\times\) time…
