I am stuck with a question. Please help:
A metal block is weighed in the air, the spring balance shows 20 N. Then a beaker with water is taken weighing 40 N. The metal block is immersed in the liquid, the apparent weight being 16 N. Thus the buoyancy recorded is 4N. So, what is the weight of beaker with water and block now?
NOTE added for clarification: While floating, the metal block remains attached to the spring balance in such a way that the spring continues to carry a load of 16 N.
In some books i have seen that they say to add the buoyant force to the original weight of beaker. But, I argue if Two blocks of different masses but same volume sink in water in separate beakers of equal weight. Then, would the weight of the beakers be the same?
