JEE Main & Advanced Physics Electro Magnetic Induction Question Bank Static EMI

  • question_answer
     The momentum in mechanics is expressed as \[m\times v\]. The analogous expression in electricity is  [MP PMT 2003]

    A)            \[I\times Q\]                        

    B)            \[I\times V\]

    C)            \[L\times I\]                         

    D)            \[3.75\times {{10}^{-2}}\,N\]

    Correct Answer: C

    Solution :

                       Magnetic flux \[\varphi =LI\]            By analogy, since physical quantities mass (m) and linear velocity (v) are equivalent to electrical quantities inductance (L) and current (I) respectively. Thus magnetic flux \[\varphi =LI\]is equivalent to momentum \[p=m\times v\].
