The following observations were taken for determining surface tension T of water by capillary method: diameter of capillary, `D = 1.25 xx10^(-2)` m and rise of water, `h -=1.45 xx10^(-2)m`. Using `g = 9.80 m//s^2` and the simplified relation` T = (rhg)/2 xx10^3` N/m, the possible error in surface tension is close to

A

`1.5%`

B

`5.5%`
