Write true or false for the following statements :
Buoyant force experienced by a body when fully immersed in air is less than that experienced by it in water.
The fluid having higher density exerts more buoyant force on an immersed body than the fluid having lower density. As water is denser than air, buoyant force experienced by a body when fully immersed in air is less than that experienced by it in water.
