  • question_answer
    If m is mass, Q is charge and B is magnetic induction, then \[\frac{m}{BQ}\]has the same dimensions as:

    A)  frequency                         

    B)  \[\frac{1}{\text{frequency}}\]

    C)  velocity                              

    D)  acceleration

    Correct Answer: B

    Solution :

                     Dimensions of\[\frac{m}{BQ}\] \[\text{=}\frac{\text{Dimensinons}\,\text{of}\,\text{m}}{\text{(Dimensions}\,\text{of}\,\text{B)(dimensions}\,\text{of}\,\text{Q)}}\] \[\frac{m}{BQ}=\frac{[M]}{[M{{L}^{0}}{{T}^{-2}}{{A}^{-1}}][{{M}^{0}}{{L}^{0}}TA]}=\frac{1}{[{{T}^{-1}}]}\] \[\text{=}\,\frac{\text{1}}{\text{frequecy}}\]
