Q)
A capillary tube of radius 'r' is immersed in water rises to a height of 'h'. Mass of water in the capillary tube is 5×10−3kg. The same capillary tube is now immersed in a liquid whose surface tension is √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)
