Water is filled in a cylindrical container to a height of `3m`. The ratio of the cross-sectional area of the orifice and the beaker is `0.1`. The square of the speed of the liquid coming out from the orifice is `(g=10m//s^(2))`.

Options

A. `50 m^(2)s^(-2)`
B. `50.5 m^(2)s^(-2)`
C. `51 m^(2)s^(-2)`
D. `52 m^(2)s^(-2)`

Answer

A

Explanation

According to eqn of continuity `aupsilon=AV`.
`P+rho gh +(1)/(2)rho upsilon^(2)=P+O+(1)/(2)rho upsilon^(2)`
