In a bucket full of water, a block weighing 50N was immersed. Water weighing 5N spilled out of the bucket. The buoyant force is
According to Archimedes' Principle, when a body is partially or totally immersed in a liquid, it experiences a buoyant force which is equal to the weight of the liquid displaced. So, when the block is immersed, it would experience a buoyant force which would be equal to the weight of the liquid displaced. Here, the weight of the displaced liquid is given 5N. So, the buoyant force is equal to 5N.
