Angle of Contact & Capillarity

If we dip capillary tubes of different radii $r_n$ in water and the water rises to different heights $h_n$ in them, then ( $n = 1, 2, 3$ .........)

Show answer and solution

Answer: (d)

$h = \frac{2T\cos\theta}{r\rho g}$ , so for the same liquid and tube material $hr = \frac{2T\cos\theta}{\rho g}$ = constant.
So the answer is (d) $h_n r_n$ = constant.
