Drops of liquid of density d are floating half immersed in a liquid of density p. If the surface tension of liquid is T, then radius of the drop will be

• A

  $\sqrt{\left\{\frac{3\mathrm{T}}{\mathrm{g}(2\mathrm{d}-\mathrm{\rho })}\right\}}$

• B

  $\left\{\frac{3\mathrm{T}}{\mathrm{g}(\mathrm{d}-\mathrm{\rho })}\right\}$

• C

  $\sqrt{\left\{\frac{6\mathrm{T}}{\mathrm{g}(2\mathrm{d}-\mathrm{\rho })}\right\}}$

• D

  $\sqrt{\left\{\frac{6\mathrm{T}}{\mathrm{g}(\mathrm{d}-\mathrm{\rho })}\right\}}$
