1. The problem statement, all variables and given/known data A cylindrical tank of radius 4cm is partly filled with water.A solid metal sphere of radius 3cm is lowered into the water by means of a thin wire until it is totally immersed. Find the increase in (i) the depth (ii) the pressure at a point on the base (iii) the thrust on the base(in terms of π ) 2. Relevant equations Pressure = (depth)(g)(density) 3. The attempt at a solution (i) h = depth of water before sphere added Volume of water before sphere added = 16(π )(h) volume after sphere added = 16(π)(h) + (4/3)(π)(64) pressure = (1)gh (since the density of water is 1/cm^3) I'm not sure what to do next I'd presume I have to get the depth(h) somehow?
