Chapter 8, Problem 2RAT

The pressure at the bottom of a pond does NOT depend on

(a) the acceleration due to gravity.

(b) water density.

(c) the depth of the pond.

(d) the surface area of the pond.

To determine

The correct option for the statement “The pressure at the bottom of pond does not depend on”.

Answer to Problem 2RAT

The correct option for the statement “The pressure at the bottom of pond does not depend on” is option (d).

Explanation of Solution

Write the expression to calculate the pressure exerted by the liquid at the bottom of pond.

$P=\rho gh$

Here,

$\rho$ is the density of liquid

$g$ is the acceleration due to gravity

$h$ is the depth of the liquid filled in the pond

From above expression, it is clear that the pressure exerted by the liquid at the bottom of the pond depends upon the acceleration due to gravity, water density and the depth of pond.

The pressure exerted by the liquid at the bottom of pond does not depend on the surface area of the pond.

Conclusion:

Therefore, the correct option for the statement “The pressure at the bottom of pond does not depend on” is option (d).
