Question

why needle sink in water but not boat​

Answer 1

Answer:

It's because an iron ship is not completely solid. ... So the average density of the ship as a whole is less than the density of water. Therefore immersed portion of the ship displaces water equal to its weight. So the ship floats whereas a sheet of iron is compact and there are no air spaces inside it.

Explanation:

Hence, according to Archimedes' principle, the upthrust is more than the weight of the ship. That is why the iron ship floats in water. The density of an iron nail is more than that of water. It displaces less water than its weight and so the nail sinks in water.
