The length of a potentiometer wire is 2.5 m and its resistance is 8Ω. A cell of negligible internal resistance and emf of 2.5 V is connected in series with a resistance of 242Ω in the primary circuit. The potential difference between two points separated by a distance of 20 cm on the potentiometer wire is
