Question

A cylindrical vessel of 90 cm height is kept filled with water upto the rim. It has four holes 1,2,3,4 which are respectively at heights of 20 cm 45 cm and 50 cm from the horizontal floor PQ. Through which of the holes water is falling at the maximum horizontal distance ?

Answer 1

Different holes of the cylindrical vessel are shown in the figure. Water comes out from different holes with different speeds. Therefore range will be different corresponding to different holes,

Horizontal range will be maximum
when `h=(H)/(2)=(90)/(2)=45 cm`
This height corresponds to hole 3.
