A 5 m potentiometer wire having 3Ω resistance per meter is connected to a storage cell of steady emf 2V and internal resistance 1Ω. A primary cell is balanced against 3.5m of it. When a resistance of 32/nΩ is put in series with the storage cell, the null point shifts to the centre of the last wire, i.e., 4.5 m. What is ‘n’?
