Solution

Let the height of the liquid-filled column be L.
Let the radius be denoted by R.

\[\text{ Total perimeter of the curved part = semi - circumference of upper area }= \pi r \]

\[\text{ Total surface tension force } = \pi RS\]

\[\text{ Total perimeter of the flat part = 2R } \]

\[\text{ Total surface tension force = 2RS }\]

\[\text{ Ratio of curved surface force to flat surface force } = \frac{\pi RS}{2RS} = \frac{\pi}{2}\]

\[\]
