SUMMARY
The potential energy of water in a symmetric wedge is calculated using the formula E = mgh, where m is the mass of the water, g is the acceleration due to gravity, and h is the height of the water. The discussion highlights the challenge of integrating the varying cross-section of the wedge, which increases linearly from 0 to A as the height h increases. The solution involves determining the center of gravity of the triangular cross-section to facilitate the integration process. The correct potential energy expression for the wedge is derived from understanding the geometry of the water's distribution.
