MCQ
When two capillary tubes of different diameters are dipped vertically, the rise of the liquid is
- ASame in both the tubes
- BMore in the tube of larger diameter
- CLess in the tube of smaller diameter
- ✓More in the tube of smaller diameter
✓
Answer
Correct option: D.
More in the tube of smaller diameter
d
(d) $h = \frac{{2T\cos \theta }}{{rdg}}\therefore h \propto \frac{1}{r}$ ($T$,$\theta$, $d$ and $g$ are constant)
(d) $h = \frac{{2T\cos \theta }}{{rdg}}\therefore h \propto \frac{1}{r}$ ($T$,$\theta$, $d$ and $g$ are constant)
If $r$ is less then $h$ will be more.
