The following observations were taken for determining surface tension T of water by capilary method:
diameter of capillary, `D = 1.25 xx 10^(-2)` m
rise of water, h ` 1.45 xx 10^(-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

A
