JEE Main & Advanced Physics Photo Electric Effect, X- Rays & Matter Waves Question Bank Cathode Rays and Positive Rays

  • question_answer
    When subjected to a transverse electric field, cathode rays move                                            [MP PET 1994]

    A)            Down the potential gradient

    B)            Up the potential gradient

    C)            Along a hyperbolic path

    D)            Along a circular path

    Correct Answer: B

    Solution :

               In an electric field, a force opposite to the direction of electric field acts on negatively charged particles (i.e. from lower potential to higher potential).
