A soap bubble of radius \( R \) is surrounded by another soap bubble of radius \( 2 R \), as shown.
\( \mathrm{P} \) Take surface tension \( =S \). Then, the pressure
W inside the smaller soap bubble, in excess of Atmostphere the atmospheric pressure, will be
(1) \( 4 S / R \)
(2) \( 3 S / R \)
(3) \( 6 S / R \)
(4) None of these
