Two soap bubbles A and B are kept in a closed chamber where the air is maintained at pressure `8N//m^2`.The radii of bubbles A and B are 2cm and 4cm, respectively. Surface tension of the soap-water used to make bubbles is `0.04N//m`. Find tha ratio `n_B//n_A`, where `n_A` and `n_B` are the number of moles of air in bubbles A and B, respectively. [Neglect the effect of gravity.]
