The balancing length for a cell is 560 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 cm. If the internal resistance of the ceil is $${N \over {10}}$$ $$\Omega$$ , where N is an integer then value of N is .............
