Does Pressure Force Change with Container Volume in Water Filled Containers?

AI Thread Summary
Pressure force in water-filled containers with equal bottom areas but different volumes is determined by the height of the water column, not the volume itself. The pressure at the bottom is calculated using the formula P = ρgh, where h is the height of the water. Since the containers have the same base area, the pressure force will vary based on the height of the water, which is influenced by the container's geometry. The discussion highlights the ambiguity in terminology, emphasizing the distinction between pressure and force. Ultimately, the key factor affecting pressure at the bottom is the water height, not the container volume.

I've got a "dilemma" here about Pressure Force:
" Containers with different volumes but with the same areas at the bottom are filled with water of equal mass. Will the Pressure Force vary according to containers?"

First of all I guess Pressure Force must be equal to the Weight [W] of water which is same for all containers W=mg=F , but on the other hand F=PxS=dghS=dgV (P-pressure, S-area at the bottom, d-density of liquid , V-volume of container) and it varies due to the volume of container.

Thanks...

pressure depends on depth

The pressure at the bottom of the container depends only the depth (h) below the surface of the water (ignoring atmospheric pressure): P = \rho g h. So what matters is the height of the water in each container. Does the water reach the same height in each container?

(The question is a bit ambiguous, since no mention is made of the shape of the containers.)
 
The problem asks about Pressure Force (not Pressure) which causes pressure P=F/S S-Area

Since the areas of the bottoms are equal, the only thing that can vary the pressure at the bottom of the containers is the height the liquid rises in each container as Doc Al already said. The height that the level rises will be dependent on the containers' geometries.

BTW..."Pressure force" is a horrible term to use. You're either interested in the pressure or the force applied.
 
I'm interested in Force applied.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
