Two soap bubbles A and B are kept in a closed chamber where the air is maintained at pressure of 8N.m^-2. The radii of bubbles A and B are 2 cm and 4 cm respectively. Surface tension of the soap water. Used to make bubbles is 0.04N.m^-1. Find the 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),
