The balancing length for a cell is $\displaystyle 560$ cm in a potentiometer experiment. When an external resistance of $\displaystyle 10 \Omega$ is connected in parallel to the cell, the balancing length changes by $\displaystyle 60$ cm. If the internal resistance of the cell is $\displaystyle \frac{\mathrm{N}}{10} \Omega$, where N is an integer then value of N is \_\_\_\_.
