Question

why does an iron ball sinks in water and where as an iron ship float on water why​

Answer 1

Since the ship is designed in such a way that its effective density (m/V) is less than the density of the water. The weight of the water displaced by the ship is equal to its weight, so it floats. Whereas the weight of the water displaced by the iron nail is less than its weight so the iron nail sinks.❤️
