Liquid drops are falling slowly one by one from vertical glass tube. The relation between the weight of a drop ' $w$ ', the surface tension ' $T$ ' and the radius ' $r$ ' of the bore of the tube is (Angle of contact is zero)

$\mathrm{W}=\pi \mathrm{r}^2 \mathrm{~T}$

$\mathrm{W}=2 \pi^2 \mathrm{rT}$

$\mathrm{W}=\left(\frac{4}{3}\right) \pi^2 \mathrm{rT}$

$\mathrm{W}=2 \pi \mathrm{r} \mathrm{T}$
