  • question_answer
               A 10 metre wire kept in east-west falling with velocity 5 m/sec perpendicular to the field\[0.3\times {{10}^{-4}}Wb/{{m}^{2}}\].  The induced e.m.f. across the terminal will be            [MP PET 2000]

    A)             0.15 V                                     

    B)            1.5 mV

    C)             1.5 V                                       

    D)            15.0 V

    Correct Answer: B

    Solution :

                       Induced e.m.f. \[=Blv=0.3\times {{10}^{-4}}\times 10\times 5\]            \[=1.5\times {{10}^{-3}}V=1.5\ mV\]
