Question

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

• A. Both assertion and reason are true and reason is the correct explanation of assertion.
• B. Both assertion and reason are true but reason is not the correct explanation of assertion.
• C. Assertion is true but reason is false.
• D. Both assertion and reason are false.

Answer 1

Answer: (D)

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 difference in the water same.
