प्रश्न
Two identical pieces, one of ice (density = 900kg per meter cube) and other wood (density = 300kg per meter cube) float on water.
- Which of the two will have more volume submerged inside water
- Which of two will experience more upthrust due to water.

उत्तर
- Ice will be more submerged inside water. Ice has a greater density than wood, although the volume of both is the same. So to support a greater amount of weight, ice needs to displace more water, and to displace more water, it has to be submerged more as compared to wood.
- As ice displaces more water, it will experience more upthrust.
