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.
