# NEET Physics Mechanical Properties of Fluids Questions Solved

A large tank is filled with water to a height H. A small hole is made at the base of the tank. It takes time ${\mathrm{T}}_{1}$ to decrease the height of water to $\frac{\mathrm{H}}{\mathrm{\eta }}\left(\mathrm{\eta }>1\right)$ ; and it takes ${\mathrm{T}}_{2}$ time to take out the rest of water. If ${\mathrm{T}}_{1}={\mathrm{T}}_{2}$, then the value of $\mathrm{\eta }$ is
(a) 2                                    (b) 3
(c) 4                                    (d) $2\sqrt{2}$
