The area of cross-section of a potentiometer wire is 6×10−7m2. The potential difference per unit length of the potentiometer wire when it is connected to a cell of negligible internal resistance and a resistor in series is 0.15Vm−1. If the current through potentiometer wire is 0.3 A , then the resistivity of the material of the potentiometer wire is
