F/A=p F=Ap I think I figured it out

here it is. Its pretty simplistic but hopefully you get the point.

Homework Statement Prove that P1>PoHomework Equations dp=-rho(g)dy integral(Po,P1)dp=-integral(Y2,Y1) rho(g)dy The Attempt at a Solution dp=-rho(g)dy intgrl(Po,P1) dp=-integral(Y2,Y1) rho(g)dy Po-P1=-(rho(g))(Y2-Y1) Po-P1=(rho(g))(Y1-Y2) Y2-Y1-->Y1-Y2<0 defined as -del(y)...

you have a plane inside of a container of water. On the plane there is the force of gravity pointing downward. F2 must point downward and F1 must point upward. There is no acceleration within the system. F1,2≈ P1,2ΔA. Does that help?

Homework Statement Why must F2=P2(deltaA)(-j hat) and the opposing force be F1=P1(deltaA)(+j hat). Prove that these are the only two possibilities that are true. Homework Equations The Attempt at a Solution
