The frequency $(v)$ of an oscillating liquid drop may depend upon radius $(r)$ of the drop, density $(\rho)$ of liquid and the surface tension $(s)$ of the liquid as : $v=r^{ a } \rho^{ b } s ^{ c }$. The values of $a , b$ and $c$ respectively are
$\left(-\frac{3}{2},-\frac{1}{2}, \frac{1}{2}\right)$
$\left(\frac{3}{2},-\frac{1}{2}, \frac{1}{2}\right)$
