A) 80 m
B) 90 m
C) 10 m
D) 70 m
Correct Answer: D
Solution :
[d] Let V be the original volume of bubble. The final volume will be 8 V. Let p be the atmospheric pressure and \[{{p}_{1}}\] the pressure at the bottom \[\therefore p\times 8V={{p}_{1}}\times V;\] \[8p={{p}_{1}}\] \[{{p}_{1}}\]= atmospheric pressure + pressure due to water lake \[=p+7p\] The p =10m high, the 7p will be = 70m high So the depth = 70mYou need to login to perform this action.
