Question

Water rises to a height h in a capillary tube of area of cross-section a. To what height will water rise in a capillary tube of radius of cross-section 4a?


  1. h4

  2. h2

  3. 2h

  4. 4h


Solution

The correct option is B

h2


Area of cross-section, a=πr2r=aπ
Now, height rise in a capillary tube is given by h=2σcos θrρg=2πσcos θaρg
As h1a, if a is increased 4 times, h will decrease by a factor of 2.
Hence, the correct choice is (b).
