A) \[200{}^\circ C\]
B) \[400{}^\circ C\]
C) \[100{}^\circ C\]
D) \[300{}^\circ C\]
Correct Answer: B
Solution :
Comparing the given equation with \[E=\alpha \,t+\frac{1}{2}\beta \,{{t}^{2}}\] We get \[\alpha =16\] and \[\frac{1}{2}\beta =-0.04\,\Rightarrow \,\,\beta =-0.08\] Þ \[{{t}_{n}}=-\frac{\alpha }{\beta }=-\frac{16}{-0.08}=200{}^\circ C\] Also \[{{t}_{i}}=2{{t}_{n}}-{{t}_{c}}\]Þ \[{{t}_{i}}=2\times (200)-0=400{}^\circ C\]
