Question

a body of mass 50g is floating in water. what is the apparent weight of body in water? explain your answer

Answer 1

apparent weight is weight in air minus upthrust of water
we need to know the volume of the object to give a perfect answer.but however to calculate,
upthrust= volumeof object*density of water *gravity(9.8)
therefore,
apparent weight=current nmass in air-upthrust

Answer 2

as the body is floating in water, it means the body is in equilibrium .

  weight m g = buoyancy force.

apparent weight =  weight in air - buoyancy force = 0
