Can you please explain the following question: A body floats in water with 2/3rd of its volume inside water. What is the the relative density ?

Expert Answer:

Dear student,
 
The mass of the body = mass of water it displaces 
V = volume of body
Ρ = density of water
.. then mass of water displaced M = (2/3V x Ρ) kg

Density of body = M/V = (2/3VP)V = 2/3Ρ.. the body has a density 2/3 that of water - 

.. it's relative density is 2/3 (relative to water)
 
 
Hope this helps.
Thankyou
