Question

The wall of a dam is made thicker at the bottom because : (a) the pressure exerted by a liquid remains the same with its depth (b) the pressure exerted by a liquid decreases with its depth (c) the pressure exerted by a liquid increases with its depth (d) of safety from outer forces.

Answer

(d) the pressure exerted by a liquid increases with its depth

Reason — A dam has broader walls at the bottom than at the top as the pressure exerted by the liquid increases with it’s depth. Thus, as depth increases, more and more pressure is exerted by water on the walls of the dam.
