Where is it easier to keep the body in the air or in the water? Why?

Any body is easier to hold in water than in air. This is due to the fact that the buoyancy force or the force of Archimedes acts on the body in water. Archimedes’ force = density of the fluid in which this body is immersed (ρ) * volume of the immersed body (V) * constant value g (9.81). That is, the larger the volume of the body, the easier it is to keep it in water. The force of Archimedes is directed opposite to the force of gravity, thereby reducing the weight of the body and making it easier to hold it. In air, only gravity acts on the body.
