Consider vertical parallel of semi-circular cross section dipped in a liquid. Assume that the wetting of the tube is
\( \mathrm{P} \) complete. The force of surface tension on the flat part and

W on curved part of the tube are in the ratio
(1) \( 2: \pi \)
(2) \( 1: \pi \)
(3) \( 3: \pi \)
(4) \( 4: \pi \)
