a$)$ Magnitude and direction of the horizontal component of the hydrostatic force acting on $AB.$

Surface is $1m$ long $($normal to page$)$

Water

b$)$ Magnitude and direction of the vertical component of the hydrostatic force acting on $AB.$

c$)$ Magnitude, direction, and line of action of the resultant hydrostatic force acting on $AB.$
