The following observations were taken for determining surface tension $T$ of water by capillary method:
diameter of capillary, $D = 1.25 \times 10^{-2} m$
rise of water, $h = 1.45 \times 10^{-2} m$
Using $g = 9.80 \ m/s^2$ and the simplified relation
$T =\frac{ rhg }{2} \times 10^3 \ N/m,$ the possible error in surface tension is closest to:
