As shown in the figure below, a circular $log0\mathrm{.}5m$ in radius and $4m$ long got stuck at the upstream side of a broad crested weir and prevents the entry of water to its downstream side. If the water raised to the top edge of the log$,$ determine the following:

$5.$The horizontal component of the hydrostatic force in $N$ acting on the left projected face of the log $($to a vertical plane$)$

a$)19,620$

b$)18,726$

c$)20,341$

d$)15,627$

$6.$ The net horizontal force in $N$ acting on the $log$ is

a$)3,426$

b$)4,567$

c$)4,905$

d$)3,398$

$7.$ The total hydrostatic vertical force acting on the log is

a$)31,456$

b$)27,898$

c$)32,944$

d$)35,672$
