Question

part a

consider three drinking glasses. all three have the same base area, 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, so it holds more water than glass a. glass c is narrower at the top than the bottom, so it holds less water than glass a. which glass has the greatest liquid pressure at the bottom?

• all three glasses have equal pressure at the bottom.
• glass a has the greatest pressure at the bottom.
• glass b has the greatest pressure at the bottom.
• glass c has the greatest pressure at the bottom.

Explanation:

Identify the hydrostatic pressure formula

$$ P = P_0 + ho g h $$

Compare the parameters for each glass

Answer:

• All three glasses have equal pressure at the bottom. (Correct answer)
• Glass A has the greatest pressure at the bottom.
• Glass B has the greatest pressure at the bottom.
• Glass C has the greatest pressure at the bottom.
