Exam points

  • Compare equal-height water columns to distinguish total fluid weight from bottom pressure.
  • Use vertical fluid depth rather than container shape to identify the greatest bottom pressure.

8.2.B—Describe the pressure exerted by a fluid question 1

[Maximum number: 1]

Compare the two columns of water pictured below. They have the same height. Which of the following statements compares the total weight and the pressure at the bottom of the columns?

Figure for Question 8.2.B—Describe the pressure exerted by a fluid question 1 — AP Physics 1: Algebra-Based
A

Weight and pressure are greater for the wider column.

B

Weight and pressure are the same for both.

C

Weight is greater for the wider column, while pressure is the same.

D

Weight is the same, while pressure is greater for the wider column.
