Water is filled in a container upto height 3m. A small hole of area 'a' is punched in the wall of the container at a height 52.5 cm from the bottom. The cross sectional area of the container is A. If `a//A=0.1` then `v^2` is (where v is the velocity of water coming out of the hole)

Options

A. `50`
B. `51`
C. `48`
D. `51.5`

Answer

A

Explanation

Apply continuity equation `A_(1)V_(1) = A_(2)V_(2)` and Bernuli theorum `(P_(0))/(rho) + (v^(2))/(2) + gh = "constant"` (at the top and at the hole)
