The wall below the dam is made thick because the pressure of the fluid increases with increasing depth. This thick wall is necessary to withstand the increased pressure exerted by the water against it as the depth increases.

The wall below the dam is made thick because the pressure of the fluid increases with increasing depth. This thick wall is necessary to withstand the increased pressure exerted by the water against it as the depth increases.
The wall below the dam is made thick because the pressure of the fluid increases with increasing depth (A). This is due to the weight of the fluid above exerting a force on the lower levels. A thicker wall is needed to withstand the greater force exerted by the fluid against it as the depth increases. This principle is described by Pascal’s law, which states that pressure applied to a fluid in a confined space is transmitted undiminished throughout the fluid. Therefore, as the depth below the dam increases, the pressure exerted by the water against the wall also increases. Option (A) accurately reflects this relationship between pressure and depth, making it the correct choice for explaining the necessity of a thick wall below the dam.
