Two capillary tubes of same material dipped are placed vertically in the same liquid. If their radii are in the ratio of 2:3, the ratio of rise of liquid in the tubes is 

• Expression for capillary rise $\mathrm{h}=\frac{2\mathrm{Tcos\theta }}{\mathrm{r\rho g}}$
• All other factors are equivalent if two capillary tubes are made of the same material and are positioned vertically. 
• Gravity, tension, and angle of contact with respect to the surface are all equal.
• Currently, the formula states that the relationship between h (height) and r is inverse (radius of tube). 
• The ratio of the height of the liquid column would be 3:2 if the ratio of the radii is 2:3.

Hence the correct answer is 3:2.
