The water or (water-beaker system) exerts an upthrust force directed upwards on the block. The water (or water-beaker system) experiences a reaction of equal magnitude from the block.
A flask of water rests on a scale that reads 100N. 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).
The experiment is repeated with the six different blocks listed below. In each case, the blocks are held completely submerged in the water.
