A capillary tube of radius $\displaystyle 0.1$ mm is partly dipped in water (surface tension $\displaystyle 70 \mathrm{dyn} / \mathrm{cm}$ and glass water contact angle $\displaystyle \approx 0^{\circ}$ ) with $\displaystyle 30^{\circ}$ inclined with the vertical. The length of water risen in the capillary is $\displaystyle \_\_\_\_$ cm. (Take $\displaystyle \mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^2$ )
