The frequency ($$\nu$$) 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 $$\nu=r^a\rho^b s^c$$. The values of a, b and c respectively are

$$\left( {{3 \over 2},{1 \over 2}, - {1 \over 2}} \right)$$

$$\left( { - {3 \over 2}, - {1 \over 2},{1 \over 2}} \right)$$
