    If the given electron has a velocity not perpendicular to B, then trajectory of the electron is:

    A) straight line                   

    B) circular

    C) helical                          

    D) zig-zag         

    Correct Answer: C

    Solution :

    (c) helical If the charged particle has a velocity not perpendicular to \[\overrightarrow{B}\], then component of velocity along \[\overrightarrow{B}\] remains unchanged as the motion along the \[\overrightarrow{B}\] will not be affected by \[\overrightarrow{B}\]. Then, the motion of the particle in a plane perpendicular to \[\overrightarrow{B}\] is as before circular one. Thereby, producing helical motion.
