Question 6

Pressure

At a fixed point below a liquid surface, the pressure downward is P1 and the pressure upward is P2. It can be deduced that

  1. A.P1 = P2
  2. B.P1 > P2
  3. C.P1 < P2
  4. D.P1 ≥ P2
Show the answer and explanation

Answer: A (P1 = P2)

Explanation

Pressure at a point in a liquid acts equally in all directions, so the downward and upward pressures at the same point are equal.
