Q.the following observations were taken for determining the surface tension T of water by capillary method: diameter of capillary,D=0.0125m rise of water, h=0.0145m. using g=9.8m/s^2 and the simplified relation T=(rhg/2)*10^3 N/m, the possible error in the surface tension is closest to:1)1.5%2)2.4% 3)10% 4)0.15% |
