A secondary cell of emf 2 V and finternal resistance 0.1 `Omega` is connected to the ends of a uniform wire of length 1 m and resistacne 12 `Omega`.A primary cell of emf 1.5 V in series with a galvancometer is connected to two points on the wire. If the galvanometer shows no deflection find the distance between the points.
