Question

A drop of liquid of density $\rho$ is floating half immersed in a liquid of density $\sigma$ and surface tension $7.5 \times 10^{-4}$ $\mathrm{Ncm}^{-1}$. The radius of drop in cm will be : (Take: $\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ )

Select the correct option:

$\frac{15}{\sqrt{2 p-\sigma}}$

$\frac{15}{\sqrt{\rho-\sigma}}$

$\frac{3}{2 \sqrt{\rho-\sigma}}$

$\frac{3}{20 \sqrt{2 p-\sigma}}$

✓ Correct! Well done.
