Question

5) A capillary tube having inner diameter 1 mm and
the outer diameter 4 mm hangs vertically from one
arm of the balance. If the lower end of the tube just
touches a liquid of surface tension 3 10N/m,
assuming that the liquid wets the tube. Find the
downward force due to surface tension acting on the
tube.(Ans: F= 4.71 x 10-N)
the swelcht of​
