Question

Three containers are used in chemistry lab. All containers have same bottom area and the same height. A chemistry student fills each of the containers with same liquid to the maximum volume. Which of the following is true about the pressure on the bottom for each container?

• A. P1>P2>P3
• B. P1
• C. P1P3
• D. P1=P2=P3

Answer 1

The correct option is D P1=P2=P3

The pressure at the bottom of the container is

$P=\frac{F}{A}=\frac{W}{A}=\frac{Ah\rho g}{A}=\rho gh$

Since the liquid filled is same, $\rho$ is same.

Also the height upto which they are filled is same. Hence $P_1=P_2=P_3$
