  • question_answer
    A uniform electric field and a uniform magnetic field are acting along the same direction in a certain region. If an electron is projected in the region such that its velocity is pointed along the direction of fields, then the electron [AIPMT (S) 2011]

    A) speed will decrease

    B) speed will increase

    C) will turn towards left of direction of motion

    D) will turn towards right of direction a motion

    Correct Answer: A

    Solution :

    [a] Field B not applied only force. Field E will apply a force opposite to velocity of the electron hence, speed will decreases.
