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)

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

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

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

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

A gardening pipe having an internal radius ' $R$ ' is connected to a water sprinkler having ' $n$ ' holes each of radius ' $r$ '. The water in the pipe has a speed ' $v$ '. The speed of water leaving the sprinkler is

$\left(\frac{\mathrm{R}^2}{\mathrm{r}^2}\right) \mathrm{nV}$

$\frac{\mathrm{R}^2 \mathrm{v}}{\mathrm{nr}^2}$

$\left(\frac{n r^2}{R^2}\right) V$

$\left(\frac{\mathrm{nR}^2}{\mathrm{r}^2}\right) \mathrm{V}$
