Question

A capillary tube of radius 5 x 10-4m is immersed in a beaker filled with mercury. The mercury level inside the tube is found to be 8 x 10-3m below the level of reservoir. Determine the angle of contact between mercury & glass. Surface tension of mercury is 0.465 N/m. & its density is 13.6 x 10 kg/m' (g 9.8 m/s2)​
