A vertically submerged rectangular gate, properly hinged and secured, whose top edge is flushed to the water surface has a width of $2m$ and a height of $3m.$ Determine the total hydrostatic force acting on the wet face, and the value of the eccentricity e$.$ Assume air is acting on the other face of the gate.

$8.$ The magnitude of the total hydrostatic force in kilonewtons is:

a$.)29\mathrm{.}9$

b$)82\mathrm{.}9$

c$)88\mathrm{.}3$

d$)92\mathrm{.}8$

$9.$ The value of the eccentricity $"e"$ in meters is

a$)0\mathrm{.}4$

b$)0\mathrm{.}3$

c$)0\mathrm{.}5$

d$)0\mathrm{.}2$

$10.$ A property of the fluid which is a measure of the fluid's resistance against shear or deformation

a$)$ surface tension

b$)$ viscosity

c$)$ elasticity

d$)$ capillary effect
