A) \[\sqrt{h(H-h)}\]
B) \[2\sqrt{h/(H-h)}\]
C) \[2(H-h)\sqrt{h/(H-h)}\]
D) \[\sqrt{2h/(H-h)}\]
Correct Answer: B
Solution :
Time taken by water to reach the foot \[t=\sqrt{\frac{2(H-h)}{g}}\] Velocity of water coming out of hole \[v=\sqrt{2gh}\] \[\therefore \] Emerging stream of water strike the foot \[x=v\times t\] \[=\sqrt{2gh}\times \sqrt{\frac{2(H-h)}{g}}\] \[=2\sqrt{h(H-h)}\]You need to login to perform this action.
