I have some questions in regards to a diagram that has a twist to the regular set up that is usually used with demonstrating Pascal's law and pistons.
In the diagram I have attached, if you added a column of water on top of the large piston which is sealed at the top from the atmosphere, there are three questions (assume the red walls of the large piston and the column on it have the same density as water):
1. I assume that even though the smaller piston on the left has an additional column of water to add pressure greater than level 2, the column of water on the large piston equalizes the hydrostatic difference and thus the large piston cannot be moved up?
2. I also assume the column size (diameter) on each of the columns doesn't matter as long as the column heights are the same?
3. If i add an incremental force down on the large piston, I can push the column of water on the small piston upward?
