Question

Four vessels 1, 2, 3, and 4 are filled with the same liquid as shown. $P_1,P_2,P_3\mathrm{and}{P}_4$ are the pressures at the base of the vessels 1, 2, 3, and 4, respectively. Which of the following options is correct?

• A. $P_2>P_1>P_4>P_3$
• B. $P_2=P_4=P_1=P_3$
• C. $P_1=P_2>P_3=P_4$
• D. $P_2=P_4>P_1=P_3$

Answer 1

The correct option is D $P_2=P_4>P_1=P_3$

$P_2=P_4>P_1=P_3$ is correct because:

• Pressure increases with the height of the liquid column.

The pressures at the base of vessels 2 and 4 are equal, and the pressures at the base of vessels 1 and 3 are equal.

Therefore, $P_2=P_4>P_1=P_3$
