(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a U-tube with cross-sectional area A and partially filled with oil of density S. A solid cylinder, which fits the tube tightly but can slide without friction, is placed in the right arm. The system is in equilibrium. Find the weight of the cylinder in terms of g, h, A, L, and S.

2. Relevant equations

I'm using these relationship ;where F is the force of the wight (F=W) & h is hight

P=F/A=W/A

delta(P) = S*g*delta(h)

3. The attempt at a solution

look at my solving and also the figure of question in attachment and tell me what is the wrong in my steps ? why h doesn't appears in the last result?

and thank you very much for your helping before
