Here is a question for you:

Support there is a container(color:orange) with mass m, and a heavy object with mass M (circle shape).

The first case: right side in the simulation

mass M is put inside the container, then let it float on top of the liquid, the liquid level rise by H.

The second case: left side in the simulation

What if the mass M is hanged under the container, then let it float on top of the liquid,the liquid level rise by h.

What is the relation between H and h

1) H>h

2) H=h

3) H<h


You can try out with the simulation. However, I would suggest you select an answer before you play with it.
