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?
i have narrowed it down to either:
a)all 3 have equal non-zero pressure at the bottom
or
b) all 3 have zero pressure at the bottom
