  • question_answer
    A charge of magnitude \[3e\] and mass \[2m\] is moving in an electric field \[\overrightarrow{E}.\] The acceleration imparted to the charge is             [DCE 2004]

    A)            \[2Ee/3m\]                           

    B)            \[3Ee/2m\]

    C)            \[2m/3Ee\]                           

    D)            \[3m/2Ee\]

    Correct Answer: B

    Solution :

               Acceleration \[a=\frac{QE}{m}=\frac{\left( 3e \right)\,E}{2m}\]
