A 10 meter long wire of uniform cross section of `20 Omega `resistance is used as a potentiometer wire. This wire is connected in series with a battery of 5V along with an external resistance of 480 Omega if an unknown emf epsilon is balanced at 600 cm of this wire , calculate the potential gradient of the potentiometer wire.
