A) \[100{}^\circ C\]
B) \[200{}^\circ C\]
C) \[300{}^\circ C\]
D) \[400{}^\circ C\]
Correct Answer: D
Solution :
Given relation, \[E=40\,t-\frac{{{t}^{2}}}{20}\] Neutral point exist where \[\frac{dE}{dt}\] will be zero. \[\therefore \] \[\frac{dE}{dt}=40-\frac{2t}{20}\] or \[40-\frac{2t}{20}=0\] or \[\frac{t}{10}=40\] \[\Rightarrow \] \[t=400{{\,}^{o}}C\]You need to login to perform this action.
