  • question_answer
    The dimension of magnetic field in M, L, T and C (Coulomb) is given as                   [AIEEE 2008]

    A) \[M{{T}^{-1}}{{C}^{-1}}\]

    B) \[M{{T}^{-2}}{{C}^{-1}}\]

    C) \[ML{{T}^{-1}}{{C}^{-1}}\]

    D) \[M{{T}^{2}}{{C}^{-2}}\]

    Correct Answer: A

    Solution :

    [a] Use \[F=iBl\]
    \[\left[ ML{{T}^{-2}} \right]=\left[ \frac{C}{T} \right]\left[ B \right]\left[ L \right]\]    \[\therefore \,\,\left[ B \right]=\left[ M{{T}^{-1}}{{C}^{-1}} \right]\]
