Question

Water rises to a height of 10cm 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 kg/m3 and angle of contact is 135^° then what is the ratio of surface tension for water and mercury? (Angle of contact for water and glass is 0^°)
