A small drop bubble of radius \( 4 \mathrm{~cm} \) is trapped inside another bubble of radius \( 6 \mathrm{~cm} \) without any
\( \mathrm{P} \) contact. Let \( P_{2} \) be the pressure inside the inner

W bubble and \( \mathrm{P}_{0} \), the pressure outside the outer bubble. Radius of another bubble with pressure difference \( \mathrm{P}_{2}-\mathrm{P}_{0} \) between its inside and outside would be :-
(1) \( 12 \mathrm{~cm} \)
(2) \( 2.4 \mathrm{~cm} \)
(3) \( 6 \mathrm{~cm} \)
(4) \( 4.8 \mathrm{~cm} \)
