Water rises upto a height $h$ in a capillary tube of certain diameter. This capillary tube is replaced by a similar tube of half the diameter. Now water will rise to a height of

Options:

Answer:

Solution:

From capillary tube experiment, We know that
$h = \frac{2 Scos θ}{r ρ g} i.e. h \propto \frac{1}{r}$
$∴ \frac{h^{'}}{h} = \frac{r}{r/ 2} = 2 or h^{'} = 2 h$
