When a long glass capillary tube of radius $0.015\mathrm{cm}$ is dipped in a liquid, the liquid rises to a height of $15 \mathrm{cm}$ within it. If the contact angle between the liquid and glass to close to $0°$, the surface tension of the liquid, in milliNewton ${\mathrm{m}}^{-1},$ is $\left[{\rho }_{\text{(liqued) }}=900 \mathrm{kg} {\mathrm{m}}^{-3},\mathrm{g}=10 \mathrm{m} {\mathrm{s}}^{-2}\right]$ (Given answer in closed integer)

Hence, the correct answer is 101.
