When a long glass capillary tube of radius $\displaystyle 0.015$ cm is dipped in a liquid, the liquid rises to a height of $\displaystyle 15$ cm within it. If the contact angle between the liquid and glass to close to $\displaystyle 0^{\circ}$, the surface tension of the liquid, in milliNewton $\displaystyle \mathrm{m}^{-1}$, is $\displaystyle \left[\rho_{(\text {liquid })}=900 \mathrm{kgm}^{-3}, \mathrm{~g}=10 \mathrm{~ms}^{-2}\right]$ (Give answer in closest integer) \_\_\_\_ .
