Find the weight of water supported by surface tension in a capillary tube with a radius of 0.2 mm. Surface tension of water is 0.072Mn^(-1) and angle of contact of water is 0^(0) .

Internal radius of a capilary tube is (1)/(2)cm and surface tension of water 70 dyne/cm, if angle of contact is zero, then water will rise up in the tube up to height.

Regarding the surface tension property of liquids, the correct statements is/are a) surface tension decreases with increase of temperature b) at 20^@ C the surface tension of ethanol is greater than that of water c) the dimensions of surface tension is SI units is Nm^(-1) d) in the fine polishing of the glass, the edges become smooth due to surface tension

Water rises to a height of 10 cm in a capillary tube and mercury falls to a depth of 3.42 cm in the same capillary tube. If the density of mercury is 13.6 g//c.c. and the angles of contact for mercury and for water are 135^@ and 0^@ , respectively, the ratio of surface tension for water and mercury is
