A ball made of iron typically sinks in water because the density of iron is greater than that of water. However, if we want to explore a scenario where an iron ball floats on water, we can consider two possible scenarios:
Hollow Iron Ball: If the iron ball is hollow, it can be designed in a way that the overall density of the ball is less than that of water. This can be achieved by adjusting the thickness and volume of the hollow portion. By making the ball buoyant, it will float on the water's surface.
Composite Ball: Another possibility is to create a composite ball using iron and materials with lower density. By combining iron with materials like foam or lightweight metals, the overall density of the ball can be reduced, allowing it to float on water.
It's important to note that both scenarios involve altering the properties of iron or combining it with other materials to achieve buoyancy. In reality, a solid iron ball would sink in water due to its high density.
