Three wires of copper, iron and nickel a...

Three wires of copper, iron and nickel are joined to form three junctions as shown in Fig. When the temperature of junction 1 is kept `50^(@)C` with the other two junctions at `0^(@)C` , the sensitive galvanometer gives a deflection of 14 divisions. When the temperature of junction 3 is kept , `50^(@)C` with the other two junctions at , `0^(@)C` the galvanometer gives a deflection of 11 divisions. Then the deflection given by the galvanometer, when temperature of the junction 2 is kept at , `50^(@)C` with the other two junctions at , `0^(@)C` will be
