A 5 m potentiometer wire having 3 Omega ...

A `5 m` potentiometer wire having `3 Omega` resistance per meter is connected to a storage cell of steady emf `2 V` and internal resistance `1 Omega`. A primary cell is balanced against `3.5 m` of it. When a resistance of `32//n Omega` 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'?
