How Does the Volume of a Block Affect Its Buoyant Force?

AI Thread Summary
The discussion centers on the relationship between a block's volume and its buoyant force when submerged in the same liquid. It questions whether different volumes of blocks affect the buoyant force experienced by each. The importance of understanding the concept of floating is emphasized, as the buoyant force acting on a floating block is equal to the weight of the liquid displaced. Participants suggest creating free body diagrams to visualize the forces acting on the blocks for better understanding. Ultimately, the buoyant force is directly related to the volume of liquid displaced, not the volume of the block itself.

Homework Statement
In each case, a block floats in a liquid. The blocks vary in mass and volume. All of the containers have the same volume of an identical liquid. Rank the buoyant force exerted by the liquid on the blocks.
Relevant Equations
Block A:
M=50g V= 100ml
Block B:
M= 50g V= 400ml
Block C:
M= 100g V= 200ml
Block D:
M=200g V=400ml
Since they're all in the same liquid I'm assuming the buoyant forces would be the same on each block. But then I think about the volumes of the blocks, and them being different. I'm not sure if the block's volume would affect the buoyant force. Any help would be great, thanks!

You are not supposed to assume that -- unless you can prove it, don't assume !

Make sketches with all relevant forces on each of the blocks (free body diagrams).
 
The most important word in the question is "floats." If a block is floating in liquid, what is the buoyant force on the block?
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
