A drop of a liquid of density

\rho

is floating half immersed inside a liquid of density

\sigma

. If the surface tension of the liquid is

T

, then the radius

R

of the drop is: (A)

R = \sqrt{\frac{3T}{g(2\rho - \sigma)}}

(B)

R = \sqrt{\frac{3T}{2g(2\rho - \sigma)}}

(C)

R = \sqrt{\frac{3T}{2g\rho}}

(D)

R = \sqrt{\frac{3T}{3g\rho}}
