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