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
Options
- A4 h R^2
- B4 h R^2
- CR^2 4 h
- Dh 4 R^2
Correct answer
C. R^2 4 h
Step-by-step solution
Velocity of efflux of liquid v= 2 g d Vertical height fall by the liquid =h Time taken by the liquid t= 2 h g Horizontal range = velocity time aligned R & = 2 g d 2 h g R^2 & =2 g d 2 h g R^2 & =4 d h d & = R^2 4 h aligned
