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 $T= \large\frac{rhg}{2}\times 10^3 N/m$, the possible error in surface tension is closest to :
