Water rises in capillary up to a certain height such that the upward force of surface tension balances the force of  $75\times {10}^{-4}\mathrm{N}$due to weight of the liquid. If surface tension of water is  $6\times {10}^{-2}\mathrm{N}/\mathrm{m}$, The internal circumference of the capillary  must be 

• A

  $1.25\times {10}^{-2}\mathrm{m}$

• B

  $0.5\times {10}^{-2}\mathrm{m}$

• C

  $6.5\times {10}^{-2}\mathrm{m}$

• D

  $12.5\times {10}^{-2}\mathrm{m}$
