A glass capillary tube is of the shape of truncated cone with an apex angle a so that its two ends have cross sections of different radii When dipped in water vertically water rises in it to a height h where the radius of its cross section is b If the surface tension of water is S its density isp and its contact angle with glass is the value of h will be g is the acceleration due to gravity 2014 Adv
