The pressure of water near bottom of the wall forming a dam does NOT depend on:
A) The depth of water
B) The cross sectional area of the reservoir
C) Density of Water
D) Atmospheric pressure
Asked by pragyagupta03 | 25th Nov, 2014, 06:36: PM
The correct option is B) The cross sectional area of reservoir.
The pressure exerted at any point in a liquid increses with depth.It also depends on the density of the liquid and the atmospheric pressure.
On the other hand pressure of a liquid does not depend upon the shape and size of the container in which it is contained.
So here the pressure of water near bottom of the wall forming a dam depends on the depth of water, density of water and atmospheric pressure whereas it is independent of the cross sectional area of the reservoir.
