प्रश्न
Why does it happen?
A ship dips to a larger depth in fresh water as compared to marine water.

उत्तर
The density of marine water is more than the fresh water due to which the buoyant force on the ship in marine water is more than the freshwater. For this reason, the ship dips to a larger depth in freshwater as compared to marine water.
