In the figure show,

find `v, t_(op)` and `R`.

Answer

A, B, C, D

Explanation

`v=sqrt(2 xx gxx "distance of orifice from top surfaace of liquid" )`
`=sqrt(2gh_(1))`
` t_(op)=`free fall time (as v is horizontal)
`=sqrt((2h_(2))/(g))` (where , `h_(2)=`free fall height)
`R=v t_(op)=(sqrt(2gh_(1)))(sqrt((2h_(2))/(g)))=2(sqrt(h_(1) h_(2)))`.
