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 :
