The following observations were taken for determining the surface tension of water by capillary tube method : diameter of capillary , $$D = 1.25 \times 10^{-2} m$$. Taking $$ g = 9.80 m s^{-2}$$ and using the relation $$T = (rgh/2) \times 10^3 Nm^{-1}$$. what is the possible error in measurement of surface tension T?


ANSWER

$$1.6\%$$
