O APPARENT WEIGHT Because of upward force acting on a body immersed in a fluid either wholly or partially there occurs an apparent loss in weight of the body The net weight of an object immersed in a fluid is called apparent weight W W Th W is the true weight of the body App Decrease in weight W WA App Note i Using Archimedes s principle we can determine relative density R D of a body as R D Th Weight of the fluid displaced density of body wt of body density of pure water at 4 C wt of equal volume of water wt of body thrust due to water wt of body loss of wt in water wt of body in air wt in air wt in water ii If a body is weighed in air WA in water W and in a liquid W loss of weight in oil WA W loss of weight in water W W then specific gravity of oil
