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