Question: A block of wood floats in a beaker of water. According to Archimedes' principle, the block experiences an?
Of course not. You got a cup of water, you add a certain mass to the system in the form of the wood. The total mass of the system will increase correspondingly.
The reason the block floats is indeed due to archimedes, but the upward bouyant force also creates a equal downward force due to the laws of Newton therefor not contributing to the total mass of the system. In general, any form of forces inside a system has no effect on the total weight of the system.
Basic newtonian physics.
It would be the same. The black displaces the water equal to its own weight. So the weight of the beaker with the water and the boat on the outside is equal to the weight of the boat in the water with the glass.
