Question

A cylinderical tank has a hole Of $2c{m}^2$ at its bottom. If the water is allowed to flow into the tank from a tube above it at the rate of $100c{m}^3/s$, then find the maximum height upto which water can rise in the tank $(Takeg=10m{s}^{-2})$

• A. $2.5\times 10^{-2}m$
• B. $1.25\times 10^{-2}m$
• C. $5.5\times 10^{-2}m$
• D. $3.5\times 10^{-2}m$
