Statement I: A ship floats higher in water on a high
pressure day than on a low pressure day.
Statement II: Floating of ship in the water is possible
because of the buoyant force which is present due to the
pressure difference.

View answer and explanation

Correct option: D

Statement I is false; Statement II is true

Option D (Statement I is false; Statement II is true) is correct because a ship's floating depends on buoyant force due to water displacement, independent of atmospheric pressure, while the statement about buoyant force is correct.
