Explanation:
Because Archimedes principle applies here !
According to him if an object is dropped in water it comes up
as object having mass => mg
so water will apply same buoyant force
If buoyant force of water = mg
object will partially shrink
if buoyant force of water < mg
object will shrink
if buoyant force of water > mg
it will float
