A bottle has a thin nozzle on top. It is filled with water, held horizontally at a height of and squeezed slowly by hands so that the water jet coming out of the nozzle hits the ground at a distance of If the area over which the handss sare which the hands squeeze it is the force applied by hands is close to (take and density of water )

- A
- Correct answerB
- C
- D
Solution

Apply Bernoulli between point- and point-
tends to zero becomes area of point- is very small.
From Kinematics.
Using (i) and (ii) we get
Hence, the correct answer is option: 'B'.
