Consider three drinking glasses. All three have thesame area base, and all three are filled to the same depth withwater. Glass A is cylindrical. Glass B is wider at the top than atthe bottom, and so holds more water than A. Glass C is narrower atthe top than at the bottom, and so holds less water than A. Whichglass has the greatest liquid pressure at the bottom?

a. Glass A

b. Glass B

c. Glass C

d. All three have equal non-zero pressure at the bottom.

e. All three have zero pressure at the bottom.

Calvin Stanton · Answer 1

The correct answer is C. All three have equal non-zero pressure

Explanation:

Pressure is the relationship between the force and the area of a body, when the bodies are liquid the formula that

P = rho g h

Where rho is the density and h the height of the liquid

We see that for this expression the pressure does not depend on the shape of the container, but on its height, as the three vessels have the same height, the pressure at the bottom is the same.

The correct answer is C All three have equal non-zero pressure
