State 1 with floating block and State 2 with sunken block.
State 1 with floating block and State 2 with sunken block.
A cylindrical container of cross-sectional area \(A\) containing water of density \(\rho_w\) rests on a table.

In State 1, a wooden block of mass \(m\) floats in static equilibrium, resulting in a total water surface height \(h_1\) above the base and a water pressure \(P_1\) at the bottom surface of the container.

In State 2, the wooden block is removed and replaced by a metal block of the same mass \(m\) and density \(\rho_m > \rho_w\) that sinks and rests on the bottom, resulting in a total water surface height \(h_2\) and a water pressure \(P_2\) at the bottom surface (away from the contact area of the metal block).

Which of the following correctly compares the water heights and the water pressures at the bottom in the two states?
