A glass disk G is held tightly against the end of a vertically held cylindrical tube C while the tube is lowered 20 cm under the water (Fig. 9.31). What is the maximum thickness the disk can have and not fall away from the cylinder? (Hint: The density of the glass is p = 25 x 10' kg/m'.) Water 20 cm G.
