A vertical tube of length 100 cm contains a mercury pallet of length 5 cm as shown in figure. The length of tube above mercury pallet if the tube is inverted is nearly: (atm pressure = 75 cm)
Text Solution
Verified by ExpertsThe correct answer is:
B
P 1 × 50 = P 2 × x
⇒ x = 
P 1 = 80 cm of Hg
P 2 = 70 cm of Hg
∴ x = 
= 57.12 cm ≈ 57 cm
