The questionnaire is indirectly stating Boyles law.....Boyles law state that the volume of a fixed mass of gas is directly proportional to the pressure if temperature is kept constant
Mathematically express as p1v1=p2v2
From the question since temperature is constant p1=p2
The answer is D please. it is true that pressure increases with depth but P1 and P2 are at the same height. Notice the question said AT A FIXED POINT.
The correct answer is A. P1 > P2.
At a fixed point below a liquid surface, the pressure downwards (P1) is greater than the pressure upwards (P2) due to the weight of the liquid above. This is based on the principle of hydrostatic pressure, which states that the pressure in a fluid at equilibrium increases with depth due to the increasing weight of the fluid above.
The pressure at a fixed point in a fluid is the same in all directions. This is known as Pascal's law. Therefore, the pressure downwards (P1) is equal to the pressure upwards (P2). So, the correct answer is:
**D. P1 = P2**
The correct answers is A
Because pressure increases with depth
So P1 is greater than P2
At a fixed point below a liquid surface, the pressure exerted downward (P1) and the pressure exerted upward (P2) are equal because pressure at a specific depth in a fluid is isotropic; i.e it acts equally in all directions. Therefore, the correct answer is:
D. P1 = P2
Also this option D reflects the fundamental property of fluids in equilibrium, where pressure at any given point is uniform in all directions.
those of you saying it is d are wrong pascal principle doesn't talk about the height or depth of the mass hydrostatic pressure does.pascal principle is just letting you know that at both depth but different position is P1=P2
so therefore the answer is A
