Question

an object weighs 400N in air and 200N in water what is the weight of the water displaced by the object

with steps

Answer 1

hi there,
objects weight on air=400N
objects weight on water =200N
therefore the weight displaced due to buoyancy =400 N-200N=200N.  
i hope this helps u..

Answer 2

the weight of the body in air = 400N
the weight of the body in water = 200N
therefore buoyancy force = 200N (400N-200N=200N)
according to Archimedes law weight of water displaced by an object is equal to the upthrust...
therefore,weight of water displaced is = 200 N
  i hope that this will help u.....................^_^
