The following observations were taken for determining surface tension T of water by capillary method:
diameter of capillary, D `= 1.25 xx 10^(-2) `m
rise of water h = `1.45 xx10^(-2)` m.
Using g =`9.80 ,m//s^(2)` and the simplified relation ` T = (rhg)/(2) xx 10^(3) N//m` , the possible error in surface tension is closest to:

If water rises in a capillary tube upto 3 cm . What is the diameter of capillary tube (Surface tension of water = 7.2 xx 10^(-2) N//m )

If the surface tension of water is 0.06 N/m, then the capillary rise in a tube of diameter 1mm is (theta=0^(@) )
