Question:medium
A square gate of size \(1\,\text{m} \times 1\,\text{m}\) is hinged at its mid-point. A fluid of density \(\rho\) fills the space to the left of the gate. The force \(F\) required to hold the gate stationary is:

Show Hint
For fluid pressure problems:
\[
p=\rho g h
\]
Always take moments about the hinge point.
