Q. The wall of a dam is made thicker at the bottom than at the top because the pressure exerted by the water on the wall
β
Correct Answer: (C)
Increases with depth of the wall
Explanation: The pressure applied to walls of the dam will be a function of the amount of water that is over that particular point on the wall. So water pressure is very large at the bottom due to its large depth. That's why dams are constructed thicker at their bottoms than at their tops.
