    The phase difference between the flux linked with a coil rotating in a uniform magnetic field and induced emf produced in it is

    A) \[f\] 

    B) \[({{f}_{pp}})\]

    C) \[({{f}_{pn}})\]                 

    D) \[({{f}_{nn}})\]

    Correct Answer: A

    Solution :

                    The flux is given by \[\text{2 m}/{{\text{s}}^{\text{2}}}\]                 \[\text{2}.\text{4 m}/{{\text{s}}^{\text{2}}}\] Also. induced emf \[\text{4}\times {{\text{1}}^{\text{-4}}}\text{ Wb}\] \[0.0\text{4Wb}\] \[\text{4}\mu \text{Wb}\]          \[\text{4}0\text{ mWb}\]
