Water rises to height of 10 cm in a certain capillary tube. If the same capillary is dipped into mercury, the level of mercury decreases to 3.42 cm. Compare the surface tension of water and mercury, if densities of mercury and water are 13.6 × 10* kg/m' and 10' kg / m³ respectively. Angle of contact for water is 0° and that for mercury is 135°.
