12th Class Physics Magnetism Question Bank MCQ - Moving Charges and Magnetism

  • question_answer
    A charged particle is released from a rest in a region, having steady and uniform electric and magnetic fields. If the two fields are parallel to each other, then the path of the particle will be:

    A) ellipse                           

    B) circle   

    C) helix                             

    D) straight line

    Correct Answer: D

    Solution :

    (d) straight line Here, \[\theta =0\] So. force due to magnetic field, \[{{F}_{m}}=0\] Hence, there is no effect of magnetic field on moving charged particle. So the particle will move due to electrostatic force only and follow straight line path.
