An object $)=(2$ is suspended by a rope and submerged at rest into two fluids as seen in the figure. The volume of the object is $1m^3$ where $0\mathrm{.}8m^3$ of the object submerged in heavier fluid. If specific weight of water is $9810\frac{N}{m^3},$ find the tension in the rope.

a$)8\mathrm{.}4kN$

b$)10\mathrm{.}4kN$

c$)16\mathrm{.}6kN$

d$)18\mathrm{.}6kN$
