An iron needle sinks in water whereas a ship made of iron floats on it because

Question 1

(a) the edge of the needle is pointed

(b) the ship is flat

(c) the ship is driven by powerful engine

(d) specific gravity of the needle is greater than that of water displaced by it.

Question 2

(a) the edge of the needle is pointed

Because the specific gravity of the needle is greater than that of water displaced by it. Specific gravity (or relative density)

= Density of the substance / Density of water at 4°C

The average density of iron needle is greater than water, therefore, it sinks.
