Physics : Archimedes Principle

1. Calculate the specific gravity of liquid from the following data:

Mass of a metal cylinder in air  = 56.8 gm

Apparent mass of the metal cylinder in water = 50.3 gm

Apparent mass of the metal cylinder in liquid = 48.7 gm

2. Determine the specific gravity of the wooden cylinder from the following data: (The metal cylinder of question 1 was used as the sinker.)                                                          

  Mass of wooden cylinder in air  = 6.9 gm               

   Apparent mass of the metal cylinder and wooden cylinder in water = 45.8 gm
