Water stands at a depth `D` behind the vertical upstream face of a dam as shown in the figure. The force exerted on the dam by water per unit width is

Water stands at a depth h behind the vertical face of a dam. It exerts a resultant horizontal force on the dam tendibg to slide it along its foundation and a torque tending to overturn the dam about the point O . Find (a) Horizontal force,(b) torque about O, (c ) the height at which the resultant force would have to act to produce the same torque,l=cross-sectional length and rho= density of water.

Water rises to a height h in a capillary tube lowered vertically into water to a depth l as shown in the figure. The lower end of the tube is now closed, the tube is the taken out of the water and opened again. The length of the water column remaining in the tube will be .
