Question

Two capillary tubes of the same material but of different radii are dipped in a liquid . the heights to which the liquid rises in the two tubes are 2.2cm and 6.6cm The ratio of radii of the tube is​

Answer 1

Answer:

Since we know that height of capillary rise is inversely proportional to radii of tube, i.e.,

$height \: \infty \frac{1}{radius}$

$\frac{h1}{h2} = \frac{r2}{r1} = \frac{2.2cm}{6.6cm} = \frac{r2}{r1}$

so,

$\frac{r2}{r1} = 3$
