An experiment on tethered mine motions is to be conducted infresh water in a wave tank. The mine is a sphere of 5cm diametermade of polystyrene (weight assumed negligible). The anchoringblock is a lead cube of side length 5cm. The specific gravity oflead is 14.0. If the mine is joined to the lead cube by a lightchord such that it floats completely submerged just below the freesurface, determine:
a) the tension in the chord
b) the reaction force between the lead cube and the bottom ofthe tank.
