Consider a water jar of radius R that has water filled up to height H and is kept on a stand of height h (see figure). Through a hole of radius r (r < < R) at its bottom, the water leaks out and the stream of water coming down towards the ground has a shape like a funnel as shown in the figure. If the radius of the cross-section of water stream when it hits the ground is x. Then: [JEE ONLINE 09-04-2016] |
A) \[x=r{{\left( \frac{H}{H+h} \right)}^{2}}\]
B) \[x=r\left( \frac{H}{H+h} \right)\]
C) \[x=r{{\left( \frac{H}{H+h} \right)}^{\frac{1}{4}}}\]
D)
Correct Answer:
D Solution :
\[x=r{{\left( \frac{H}{H+h} \right)}^{\frac{1}{2}}}\]
