If the time period tt of the oscillation of a drop of liquid of density dd, radius rr, vibrating under surface tension ss is given by the formula t=r2bscda/2t=\sqrt{r^{2 b} s^c d^{a / 2}}. It is observed that the time period is directly proportional to ds\sqrt{\frac{d}{s}}. The value of bb should therefore be :
