Relative density of mercury is 13.6. What is its density in SI unit?

Describe briefly how can you arrive at Archimedes’ principle theoretically.

How can you determine the relative density of a body using Archimedes’ principle?

Calculate the mass of a body whose volume is 2 m and relative density is 0.5.

A solid weighs 50 gf in air and 45 gf when completely immersed in water. Calculate

(i) upthrust

(ii) volume of the solid

(iii) relative density of the solid.
