JEE Main 2016 (Online) 9th April Morning Slot Physics - Properties of Matter Question 244 English Consider a water jar of radius R that has water filled up to height H and is kept on astand 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 :
  1. A
    x=r(HH+h)x = r\left( {{H \over {H + h}}} \right)x=r(H+hH​)
  2. B
    x=r(HH+h)12x = r{\left( {{H \over {H + h}}} \right)^{{1 \over 2}}}x=r(H+hH​)21​
  3. C
    x=r(HH+h)14x = r{\left( {{H \over {H + h}}} \right)^{{1 \over 4}}}x=r(H+hH​)41​
  4. D
    x=r(HH+h)2x = r{\left( {{H \over {H + h}}} \right)^{{2}}}x=r(H+hH​)2
