A low-density block with a weight of 10.0 N is placed in a beakerofwater and tied to the bottom of the beaker by a vertical stringoffixed length. When the block is 25% submerged, the tension inthestring is 16.0 N. The string willbreak if its tension exceeds 65.0N. Aswater is steadily added to the beaker, the block becomes moreandmore submerged.
(a) What percentage of the block is submerged at the instantthestring breaks?
1 %
(b) After the string breaks and the block comes to a newequilibriumposition in the beaker, what fraction of theblockâs volume issubmerged?
2 %
