Question
(f) Here is another question somewhat related to the balloon problem discussed above. A beaker of water rests on a chunk of styrofoam in a tank of water, as seen in the picture given in the next page. The water level in the tank is marked by the top of the two strips of black tape near the sides of the tank. Now we will lift the beaker of water off 1 Assuming this is done without disturbing the balance. the styrofoam float, pour all of the water into the tank, and replace the beaker on top of the styrofoam. In other words, we are transferring the water in the beaker into the tank, keeping everything else the same. The question is, where will the water level in the tank be after this action? Will the water level be lower, higher, or remain the same? Provide adequate reasonings.Explanation / Answer
It will remain at the same position.
Because when the water is in the beaker at that time also its weight was balanced by the buoyancy force that means water must be displaced equal to the weight of the water in the beaker.
hence when we pour that water into tank it will reach to the same level.
