A glass capillary sealed at the upper end is of length 11 cm and internal diameter . This tube is immersed vertically into a liquid of surface tension . When the length (cm) of the tube is immersed in liquid then the liquid level inside and outside the capillary tube becomes the same, then the value of x is : (Assume atmospheric pressure is ). Answer to nearest integer.

Answer:
1
Solution:

If final pressure of gas in tube is then (as levels inside and outside are same) i.e.

But as temperature remains constant
