  • question_answer
    A charged particle moves along a circle under the action of magnetic and electric fields, then this region of space may have:

    A) \[E=0,\,B=0\]               

    B) \[E=0,\,B\ne 0\]

    C) \[E\ne 0,\,B=0\]            

    D) \[E\ne 0,\,B\ne 0\]

    Correct Answer: B

    Solution :

    (b) \[E=0,\,B\ne 0\] A charged particle moves in a straight line under the action of an electric field whereas it moves in a circular path under the action of a magnetic field. Thus, for the particle moving in a circular path. \[E=0,\,B\ne 0\].
