    If\[E=at+b{{t}^{2}},\] what is the neutral temperature?

    A)  \[-\frac{a}{2b}\]                             

    B)  \[+\frac{a}{2b}\]

    C)  \[-\frac{a}{b}\]                                

    D)  \[+\frac{a}{b}\]

    Correct Answer: C

    Solution :

    At temperature of inversion E is minimum,\[E=0\] \[E=at+b{{t}^{2}}\] \[0=a{{t}_{1}}+bt_{1}^{2}\] \[{{t}_{i}}=\frac{-a}{b}\]
