If the diameter of a capillary is doubled then the rise of water in it will be (a) two times (b)half (c) four times (d) no change
Option B. Radius of a capillary tube is inversely proportional to the peak of the liquid column. So, if radius of the tube is doubled, upward push of degree of water will turns into 1/2 of of the preceding upward thrust in capillary tube. Capillary action, or capillarity, is the capacity of a liquid to go with the drift in slender areas with out the help of, and in competition to outside forces like gravity. The impact may be visible withinside the drawing up of beverages among the hairs of a paint-brush, in a skinny tube, in porous substances consisting of paper, in a few non-porous substances including liquefied carbon fiber, or in a cell. It happens due to inter-molecular appealing forces among the liquid and stable surrounding surfaces.
