**Inside the water, body weights two times less than in air. Density of water is 1000kg/m^3. Find the density of body.**

1. Well I tried this solution and i'm not sure if it's correct. I started from this principle [tex]Fa=W/2[/tex] (inside water force equals weight of the body divided by two). Then:

[tex]\rho 1[/tex] -> density of water

[tex]\rho 2[/tex] -> density of body

[tex]V[/tex] -> volume

[tex]\rho 1 gV=\dfrac{\rho 2gV}{2}[/tex]

[tex]\rho 1=\dfrac{\rho 2}{2}[/tex]

[tex]\rho 2=2\rho 1[/tex]

Anything wrong?

Thank you.
