Any boat will sink if it displaces water equal to its weight. According to Archimedes’ principle, the buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. Therefore, ...
The reason for a piece of iron not floating on the surface of water is that the weight of water displaced by iron is less than the weight of iron. According to Archimedes’ principle, for an object to float, the ...
