2. Volume of the cork immersed in water

Answer / Solution

UNSOLVED

1. State Archimedes’ principle.
2. A body weighs 10 N in air and 8 N when completely immersed in a liquid of density 0.8 g/cm ³ . Find:
   (i) The volume of the liquid displaced.
   (ii) The density of the body.

Answer / Solution

UNSOLVED

An object weighs 500N in air and 400N when immersed in alcohol. Find the upthrust on the object.

Answer / Solution

UNSOLVED

1. Distinguish between upthrust and apparent weight.
