We have that the density of the fluid is
[tex]\rho_f=178.57 kg/m3[/tex]
From the question we are told that
object of volume 0.0004m^3
density 6000kg/m^3
fluid of density 5000kg/m^3.
Force F=0.7N
Generally the equation for the Force is mathematically given as
[tex]F= v*\rho_f*g\\\\0.7= 0.0004*\rho_f*9.8\\\\\rho_f=\frac{0.7}{0.0004*9.8}[/tex]
[tex]\rho_f=178.57 kg/m3[/tex]
