A) \[300{}^\circ C\]
B) \[400{}^\circ C\]
C) \[100{}^\circ C\]
D) \[200{}^\circ C\]
Correct Answer: D
Solution :
\[E=20Q-\frac{{{Q}^{2}}}{20}\] \[Q={{Q}_{n}},\frac{dE}{dQ}=0\] \[\frac{dE}{d\theta }=20-\frac{2{{Q}_{n}}}{20}=0\] \[{{Q}_{n}}={{200}^{\circ }}C\]You need to login to perform this action.
