Momentum and CollisionHard
Question
When a capillary tube is dipped in a liquid, the liquid reties 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 : -
Options
A.The liquid will come out of the tube like in a small fountain.
B.The liquid will ooze out of the tube slowly.
C.The liquid will fill the tube but not come out of its upper end.
D.The free liquid surface inside the tube will not be hemispherical.
Solution
The angle of contact at the free liquid surface inside the capillary tube will change such that the vertical component of the surface tension forces just balance the weight of the liquid column.
