The upthrust of a wooden block and on an iron block, of identical dimensions, when fully immersed in water will be________.

Open in App

Solution

Density of wood is less than water and the density of iron is greater than water would have to experience more buoyancy.
Irrespective of the material mass of objects, the upthrust on the identical dimensions will always be the same because their volumes are equal.
Hence, the upthrust of a wooden block and on an iron block, of identical dimensions, when fully immersed in water will be same.
