Question 9

Pressure

Which of the following statements about liquid pressure is NOT correct? The pressure

  1. A.at a point in a liquid is proportional to the depth
  2. B.at any point in a liquid is the same at the same level
  3. C.is exerted equally in all directions at any point
  4. D.of a liquid at any point on the wall of its container acts in a direction perpendicular to the wall.
  5. E.at a particular depth depends on the shape of the vessel.
Show the answer and explanation

Answer: E (at a particular depth depends on the shape of the vessel.)

Explanation

Liquid pressure depends only on depth, density and g (p = hρg), not on the shape of the container.
