A 2m long tube closed at one end is lowered vertically into water until the closed end is flush with the water surface. See figure below. Calculate 'h' as shown in fig.
(Barometric pressure = 1atm = 10 m of hydrosatic water head, tempt.= 25ºC, density of water = 1g/ml, Neglect water vapour pressure)
Text Solution
Verified by ExpertsThe correct answer is:
C
Applying Boyle's law
P 1 V 1 = P 2 V 2
10 × 2 = (10 + h) × h
⇒ h = 1.71 m
