Explanation:
• The given assertion states that a boat built with sheet metal on a wooden frame will float in water with its hollow face upward if its average density is greater than that of water. This is because the buoyant force acting on the boat is equal to the weight of the displaced water.
• The reason given for this assertion is that buoyant force always acts in the upward direction. This is true, as per Archimedes' principle which states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.
• However, the reason alone does not explain why the boat will sink once it overturns. This is because when the boat overturns, its hollow face will be submerged in water, and the weight of the boat will increase due to the weight of the water it displaces. If this weight exceeds the buoyant force acting on the boat, it will sink.
• Therefore, both assertion and reason are individually true, but the reason alone is not a sufficient explanation for the assertion. Hence, option B is the correct answer.
