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