Ex. 3: A capillary tube having inner diameter 2
mm and the outer diameter 6 mm hangs
vertically from one arm of the balance. If the
lower end of the tube just touches a liquid of
surface tension 4 x 102 N/m, assuming that the
liquid wets the tube. Find the downward force
due to surface tension acting on the tube,
