Will there be loss of weight due to upward force of water at the bottom of the water column

Solution 
For an object immersed in water, it experiences a loss in weight. It is due to upthrust or buoyant force experienced by it. The experienced weight inside accounts for apparent weight which is given by,
Apparent weight = weight of object - buoyant force.
Buoyant force is further calculated using Archimedes' principle.
