A flask of water rests on a scale that reads 100 N. Then, a small block of unknown material is held completely submerged in the water. The block does not touch any part of the flask, and the person holding the block will not tell you whether the block is being pulled up (keeping it from falling further) or pushed down (keeping it from bobbing back up). Assume that no water spills out of the flask. What is the new reading on the scale?
a) greater than 100 N
b) 100 N
c) less than 100 N
d) It is impossible to determine.
