152632 The thermo emf of a hypothetical thermocouple varies with the temperature $\theta$ of hot junction as
$E=\mathbf{a} \theta+\mathbf{b} \theta^{2}$ In volts, where the ratio $\frac{\mathrm{a}}{\mathrm{b}}$ is $700^{\circ} \mathrm{C}$,
If the cold junction is kept at $0^{\circ} \mathrm{C}$, then the neutral temperature is

1 $700^{\circ} \mathrm{C}$
2 $1400^{\circ} \mathrm{C}$
3 $390^{\circ} \mathrm{C}$
