If you dive underwater, you notice an uncomfortable pressure on your eardrums due to the increased pressure. The human eardrum has an area of about 70 mm2(7 × 10-5 m2), and it can sustain a force of about 7 N without rupturing. If your body had no means of balancing the extra pressure (which, in reality, it does), what would be the maximum depth you could dive withoutrupturing your eardrum?A. 0.3 m             B. 1 m            C. 3 m           D. 10 m
