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 $50℃$ with the other two junctions at $0℃$, the sensitive galvanometer gives a deflection of $14$ divisions. When the temperature of junction $3$ is kept $50℃,$ with the other two junctions at $0℃,$ the galvanometer gives a deflection of $11$ divisions. Then the deflection given by the galvanometer, when temperature of the junction $2$ is kept at $50℃,$ with the other two junctions at $0℃,$ will be
