$\frac{a b}{b-a}$

Vedclass · Answer

Let say $P_{1}$ and $P_{2}$ are the excess pressure on the two sides of the interface then the resultant excess pressure is $P$

$\Rightarrow P=P_{2}-P_{1}$

$\Rightarrow \frac{4 T}{r}=\frac{4 T}{r_{2}}-\frac{4 T}{r_{1}}$

$\Rightarrow \frac{1}{r}=\frac{1}{r_2}-\frac{1}{r_1}$

$\Rightarrow r=\frac{r_{1} r_{1}}{r_{1}-r_{2}}$
