If a small orifice is made at a height ...

If a small orifice is made at a height of 0.25 m from the ground, the horizontal range of water stream will be : -

A

`46.5 cm`

B

`56.6 cm`

C

`76.6 cm`

D

`86.6cm`

Text Solution

Verified by Experts

The correct Answer is:
D
`V = sqrt(2gh) = sqrt(2 xx 10 xx 0.75) = sqrt(15)`
Horizontal range `= V sqrt((2H)/(g)) = sqrt(15) sqrt((2 xx0.25)/(10)) = sqrt(15/20) = sqrt(3/4)`
`= (1.732)/(2) = 0.866 m`
