A capillary tube of radius 'r' is immersed in water and water rises to a height of 'h'. Massof water in the capillary tube is 5xx10^(-3)kg. The same capillary tube is now immersed in a liquid whose surface tensionis sqrt(2) times the surface tension of water. The angle of contact between the capillary tube and this liquid is 45^(@). The mass of liquid which rises into the capillary tube now is, (in kg)
