A vertical capillary tube with inside radius 0 25 mm is submerged into water so that the length of its part protruding over the water surface is equal to 25 mm Surface tension of water is 73 x 10 N m and angle of contact is zero degree for glass and water acceleration due to gravity is 9 8m s Then value of 10R approximately in mm is where R is radius of meniscus and his height of water in capillary tube
