When a capillary tube is dipped in a liquid, the liquid rises to a height h in the tube. The free liquid surface inside the tube is hemispherical in shape. The tube is now pushed down so that the height of the tube outside the liquid is less than `h`. ThenA. the liquid will come out of the tube like in a small fountainB. The liquid will oze out of the tube slowlyC. the liquid will fill the tube but not come out of its upper endD. the free liquid surface inside the tube will not hemispherical.

Answer» Correct Answer - C::D
