If h is the height of the capillary rise and r be the radius of capillary tube,

If h is the height of the capillary rise and r be the radius of capillary tube, then which of the following relation will be correct?

Options

(a) hr=constant
(b) h/r²=constant
(c) hr²=constant
(d) h/r=constant

Correct Answer:

hr=constant

Explanation:

The height h to which the liquid rises in a capillary tube is given by h= (2T cosθ)/rρg
Since T, cosθ, ρ and g are constants,
.·. hr = constant.
