If any value missing please assume it. 16. A metal block 30 cm square and 25 cm deep is allowed to float on a body of liquid whichconsist of 20 cm layer of water above a layer of mercury. The block weighs 18,850 N/cu.m.What is the position of the upper level of the block? If a downward vertical force of 1110N is applied to the centroid of the block, what is the new position of the upper level of theblock?
