As the density of an iron nail is more than that of water, the nail sinks in water. The volume of water displaced is much greater than the volume of the iron ship. Hence, according to Archimedes' principle, the upthrust is more than the weight of the ship. That is why the iron ship floats in water.

sha30: volume of displacer is always equal to volume of displaced fluid so plz rethink
sha30: actually in order to sink a ship has to displace lot of water whose weight will b more than the wt. of ship which is not possible so ship can not sink.....we cant say a ship displaces lot of water once it does it will sink

Heya friend!
Here's ur answer!

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. Whereas an iron ship has more surface area and therefore the volume of water displaced is much greater than the volume of the iron ship or the upthrust is more or equal than the weight of the ship. That is why the iron ship floats in water whereas iron nail doesn't.

HOPE THIS HELPS!!☺
Thanks!!☺

sha30: remember one thing for ever....volume of submerged part of a body is always equal to volume of displaced fluid.....so plz rethink
Anushkasampa123: I know
Anushkasampa123: But the weight of the nail is less than the density of water.
sha30: again u can compare a bird with bird only so u cant compare ones weight with others density
Anushkasampa123: It would be The density of the nail
