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 5 0 to the power of o end exponent C with the other two junctions at 0 to the power of o end exponent C, the sensitive galvanometer gives a deflection of 14 divisions. When the temperature of junction 3 is kept 5 0 to the power of o end exponent C comma with the other two junctions at 0 to the power of o end exponent C comma the galvanometer gives a deflection of 11 divisions. Then the deflection given by the galvanometer, when temperature of the junction 2 is kept at 5 0 to the power of o end exponent C comma with the other two junctions at 0 to the power of o end exponent C comma will be
