Question

Consider three drinking glasses. All three have the same area base, and all three are filled to the same depth with water. Glass A is cylindrical. Glass B is wider at the top than at the bottom, and so holds more water than A. Glass C is narrower at the top than at the bottom, and so holds less water than A. Which glass 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.

Explanation / Answer

Option-D) All three have equal non-zero pressure at the bottom.

The pressure at the bottom is not determined by the amount of water in the glass but by the depth of the liquid.
