Answer:
1.If density of material of body is equal to density of liquid, the body floats fully submerged in liquid in neutral equilibrium. 2. When body floats in neutral equilibrium, the weight of the body is equal to the weight of displaced liquid.
It is easier to swim in sea water than in river water because we observe more buoyant force in sea water due to its hardness than in river water.
