THE CORrect option is (b) = 0
 
\\F_{horizontal}=0.5(9.81)(2)(2)=19.62kN
 
It will act at
   1-\frac{2}{3}=\frac{1}{3}    
from the hinge
 
\\F_{vertical}=\pi \times \frac{(1)^2}{2}(9.81)=\frac{9.81\pi}{2}kN
 
It will act at     \\\frac{4}{3\pi}    from the hinge
 
Take moments anout hinge.
\\19.62\times\frac{1}{3}-\frac{9.81\pi}{2}\times \frac{4}{3\pi}=F\times1 \\ \\\frac{19.62}{3}-\frac{19.62}{3}=F \\ \\F=0
