Question 14
PressureWhich of these statements are correct for the pressures in liquids?
I. Pressure in a liquid at a point acts equally in all directions
II. Pressure increases with depth
III. Pressure at a depth depends on the shape of the container
IV. Pressure at the same depth in different liquids are proportional to the densities of the liquids.
- A.I, II and III only
- B.I, II and IV only
- C.I, III and IV only
- D.II, III and IV only
Show the answer and explanation
Answer: B (I, II and IV only)
Explanation
Liquid pressure p = hρg acts equally in all directions, grows with depth h and is proportional to density ρ. It does not depend on the container's shape, so III is false.
