An open pan P filled with water `(density rho_m)` is placed on one side of the pan as shwon. Water depth is more then height. Of the block.

An open pan P filled with water of density (rho_w) is placed on a vertical rod, maintaining equilibrium. A block of density rho is placed on one side of the pan as shown. Water depth is more then height of the block.

A cylindrical tank has a hole of diameter 2r in its bottom. The hole is covered wooden cylindrical block of diameter 4r, height h and density rho//3 . Situation I: Initially, the tank is filled with water of density rho to a height such that the height of water above the top of the block is h_1 (measured from the top of the block). Situation II: The water is removed from the tank to a height h_2 (measured from the bottom of the block), as shown in the figure. The height h_2 is smaller than h (height of the block) and thus the block is exposed to the atmosphere. Find the minimum value of height h_1 (in situation 1), for which the block just starts to move up?
