A solid uniform ball having volume V and density `rho` floats at the interface of two unmixible liquids as shown in Fig. 7(CF).7. The densities of the upper and lower liquids are `rho_(1)` and `rho_(2)` respectively, such that `rho_(1) lt rho lt rho_(2)`. What fractio9n of the volume of the ball will be in the lower liquid.

A

`(rho-rho_(2))/(rho_(1)-rho_(2))`

B

`(rho_(1))/(rho_(1)-rho_(2))`

C

`(rho_(1)-rho)/(rho_(1)-rho_(2))`

D

`(rho_(1)-rho_(2))/(rho_(2))`
