Question

When two capillary tubes of different diameters are dipped vertically, the rise of the liquid is

• A. Same in both the tubes
• B. More in the tube of larger diameter
• C. Less in the tube of smaller diameter
• D. More in the tube of smaller diameter

Answer 1

Answer: (D)

More in the tube of smaller diameter

Answer 2

$h = \frac { 2 T \cos \theta } { r d g } \therefore h \propto \frac { 1 } { r }$ (T,θ, d and g are constant)

If r is less then h will be more.
