Tweet

Puzzle: There is a boat on the water. There is a rock in it. At this time, assume the level of the water is L1. Now say, you threw the rock into the water and it reached the bottom. Now what will be the level of the water? Solution: Show Solution when the rock was on boat the amount of water displayed by it was equal to the volume of water equal to rocks mass (Archimedes Principle). When the rock sinked to the bottom the amount of water displayed by it was equivalent to the volume of the rock. and that would imply the level of water will decrese, since the volume of rock will be less than the volume of water equivalent to that weight to the rock.
