Question

if the radius of the capillary tube is doubled, what changes will take place in the hieght of rise of liquid with capacity tube ?​

Answer 1

Explanation:

The height of the rise of liquid with capillary tube is given by the formula as follows :

$h=\dfrac{2S\cos\theta}{r\rho g}$

Where

r is radius

It is clear that the height of the rise of liquid is inversely proportional to the radius of the capillary tube.

If the radius of the capillary tube is doubled, it means the height of rise of liquid with capillary tube become half.
