JEE Main & Advanced Physics Magnetic Effects of Current / करंट का चुंबकीय प्रभाव Question Bank Motion of Charged Particle In Magnetic Field

  • question_answer
    A charged particle enters a magnetic field H with its initial velocity making an angle of \[45{}^\circ \] with H. The path of the particle will be          [MP PET 1999; AIIMS 1999; BHU 1999]

    A)            A straight line                      

    B)            A circle

    C)            An ellipse                              

    D)            A helix

    Correct Answer: D

    Solution :

               The component of velocity perpendicular to H will make the motion circular while that parallel to H will make it move along a straight line. The two together will make the motion helical.
