  • question_answer
    A charge q is placed at the center of the open end of a cylindrical vessel. The flux of the electric filed through the surface of the vessel is

    A) zero                  

    B)        \[q/{{\varepsilon }_{0}}\]

    C) \[q/2{{\varepsilon }_{0}}\]         

    D)        \[2q/{{\varepsilon }_{0}}\]

    Correct Answer: A
