A liquid drop of density ' $\rho$ ' is floating half immersed in a liquid of density ' $d$ '. If ' $T$ ' is the surface tension then the diameter of the liquid drop is ( $\mathrm{g}=$ acceleration due to gravity)

$\left[\frac{6 \mathrm{~T}}{g(2 p-d)}\right]^{\frac{1}{2}}$

$\left[\frac{8 \mathrm{~T}}{3 \mathrm{~g}(2 \rho-\mathrm{d})}\right]^{\frac{1}{2}}$

$\left[\frac{12 \mathrm{~T}}{\mathrm{~g}(2 \rho-\mathrm{d})}\right]^{\frac{1}{2}}$

$\left[\frac{3 T}{g(2 p-d)}\right]^{\frac{1}{2}}$
