The adjoining figure shows the connection of potentiometer experiment to determine internal resistance of a leclanche cell. When the cell is an open circuit the balancing length of the potentiometer wire is 3 .4m and on closing the key K_2 the balancing length becomes 17.m. If the resistance R through which current is dream is 10 Omega then the internal resistance of the cell is:
