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