Question
A capillary of the shapes as shown is dipped a liquid. Contact angle between the liquid and the capillary is 0o and effect to liquid inside the meniscus is to be neglected. T is surface tension of the liquid, r is radius of the meniscus, g is acceleration due to gravity and r is density of the liquid then height h in equilibrium is :
Options
A.Greater than 
B.Equal to
C.Less than
D.Of any value depending upon actual value
Solution
For uniform radius tube in balanced condition
But weight of liquid in tapered tube is more than uniform tube of radius r then for balanced condition
h < h1 ⇒ h <
But weight of liquid in tapered tube is more than uniform tube of radius r then for balanced condition
h < h1 ⇒ h <
