Short Answer

A right triangle is submerged vertically with one side at the surface in a liquid of density $\rho$ . The triangle has a leg that is 5 m long located at the surface and a leg 5 m long straight down. Find the force exerted on the triangular surface, in terms of the density. Neglect the effect of the atmosphere above the liquid.
