A flask of water rests on a scale thatreads 100 NN. Then, a small block of unknownmaterial is held completely submerged in the water. The block doesnot touch any part of the flask, and the person holding the blockwill not tell you whether the block is being pulled up (keeping itfrom falling further) or pushed down (keeping it from bobbing backup). Assume that no water spills out of the flask. (Figure1)

Rank these blocks on the basis of the scale reading when theblocks are completely submerged.

Rank from largest to smallest. To rank items as equivalent,overlap them.

A, B, C, D, E, F

If the blocks were released while submerged, which, if any,would sink to the bottom of the flask?
