If the pin hole in the container is very small compared to the area of the base of container and a block floats in the ideal liquid then, the speed of efflux is

Options:

Answer:

Solution:

Applying Bernoulli's theorem between free surface and orifice,
$p_{0} + \frac{1}{2} ρ V^{2} + ρ g h = p_{0} + \frac{1}{2} ρ v^{2}$
$A > > a$
So, $V < < v$
$v = \sqrt{2 g h}$
