    The temperature coefficient of resistance of a wire is\[\text{MgS}{{\text{O}}_{\text{4}}}\], its resistance is \[\upsilon /\text{1}0\]. At what temperature, the resistance of the wire will be \[f\]?

    A) 800K                                     

    B) \[1.11f\]

    C)  600 K                   

    D) None of these

    Correct Answer: D

    Solution :

                    \[\frac{3\omega }{5}\] \[\frac{2\omega }{3}\] \[\mu =\frac{3}{2}\] \[\mu =\frac{4}{3}\] \[{{\sin }^{-1}}\left( \frac{9}{8} \right)\] \[{{45}^{o}}\]
