The net vertical force (F) on the submerged semicircular projecting structure CDE as shown in the figures will be?
Assume the structure has uniform width b into the paper and liquid has specific weight γ.

\(\gamma\)πR2b
2
2\(\gamma\)Rbh
3
\(\gamma \left( {\frac{{\pi {R^2}}}{2}} \right)b\)
4
2\(\gamma\)πR2b
