  • question_answer
    In the following figure two parallel metallic plates are maintained at different potential. If an electron is released midway between the plates, it will move

    A)  right ward at constant speed

    B)  left ward at constant speed

    C)  accelerated right ward

    D)  accelerated left ward

    Correct Answer: D

    Solution :

    Electric field is directed right ward (higher potential of \[-200V\] to lower potential of\[-400V\]). When electron left free in an electric field it accelerates opposite to the electric field. Hence, in the given case electron accelerates left ward.
