Link this two principle : Archimedes Principle and Principle of Equilibrium of Forces
Answer : When an object is floating or hanging in a liquid the total force upwards and total force downwards is the same.
so if an object is floating :
bouyancy force = weight of the object
and if its hanging on a spring balance:
bouyancy force + tension on the spring = weight of the object
