Answer:
Ans. 13.6 cm
Explanation:
Pressure difference between lungs of student and atmosphere=760 - 750 = 10 mm of Hg
hdg = 10 mm of Hg = 1 cm of Hg
This pressure can only be used to drink water.
1 cm of Hg = pressure difference due to water column
=> 1 x 13.6 x g = h x 1 x g. [d of Hg=13.6 g/cm3]
=> 1 x 13.6 = h x 1
=> h = 13.6 cm
