Question
A glass capillary sealed at the upper end is of length 0.11 m and internal diameter 
m. The tube is immersed vertically into a liquid of surface tension 
N/m. To what length has the capillary to be immersed so that the liquid level inside and outside the capillary becomes the same?
- 1cm
- 2cm
- 3cm
- 4cm
The correct answer is: 1cm
