A current of 1.0 mA is flowing through a potentiometer wire of length 4 m and of resistance 4 Omega , find the potential gradient of potentiometer wire

In a potentiometer experiment, it is found that no current passes through the galvanometer when the terminals of the cell are connected across 52 cm of the potentiometer wire. If the cell is shunted by a resistance of 5 Omega the balance point is found at 40 cm of the wire from the same end. The internal resistance of the cell is
