Excess Pressure: Drops & Bubbles

The excess pressure inside the first soap bubble is three times that inside the second soap bubble. The ratio of the volume of the first soap bubble to the volume of the second soap bubble is

Show answer and solution

Answer: (d)

$\Delta P \propto \frac{1}{R}$ ; $\Delta P_1 = 3\Delta P_2 \Rightarrow R_1 = \frac{R_2}{3}$ .
$\frac{V_1}{V_2} = \left(\frac{1}{3}\right)^3 = \frac{1}{27}$
So the answer is (d) $1 : 27$ .
