A capillary tube of radius 5 x 10-4 m is immersed in a beaker filled with mercury. The mercury level inside tube
is found to be 8 x 10-3 m below the level of reservoir. Determine the angle of contact between mercury and glass.
Surface tension of mercury is O.465 N/m and its density is 13.6 x 103 kg/m3
(g = 9.8)

Explanation:
ension of mercury, if the mass density of mercury is ρ = 13.6 ... A capillary tube of radius 0.5mm is immersed in a beaker of mercury. The level inside the tube is 0.8cm below the level in beaker and angle of contact is 120o. ... of mercury is ρ=13.6×103kgm−3 and acceleration due to gravity is g=10m/s2?
