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 \[{{50}^{o}}C\] with the other two junctions at \[{{0}^{o}}C\], the sensitive galvanometer gives a deflection of 14 divisions. When the temperature of junction 3 is kept \[{{50}^{o}}C,\]with the other two junctions at \[{{0}^{o}}C,\] the galvanometer gives a deflection of 11 divisions. Then the deflection given by the galvanometer, when temperature of the junction 2 is kept at \[{{50}^{o}}C,\] with the other two junctions at \[{{0}^{o}}C,\] will be
