Assertion : A ship floats higher in the water on a high pressure day than on a low pressure day.Reason : Floating of ship in the water is not possible because of buoyancy force which is present due to pressure difference.

The level of floating of a ship in the water is unaffected by the atmospheric pressure. It depends on buoyancy force which results from the pressure difference in the fluid. If the atmospheric pressure changes, the pressure at all points in the water changes by same amount keeping pressure differnce in the water same.
