Properties of Matter question

2009 · Shift 2 · Q51

JEE AdvancedPhysicsProperties of MatterNumerical+3 / −1
Two soap bubbles A and B are kept in a closed chamber where the air is maintained at pressure 8 N/m 2^22. 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 0.04 N/m. Find the ratio nB/nAn_B/n_AnB​/nA​, where nAn_AnA​ and nBn_BnB​ are the number of moles of air in bubbles A and B, respectively. (Neglect the effect of gravity.)
