  • question_answer
    A positively charged particle is released from rest in an uniform electric field. The electric potential energy of the charge

    A) remains a constant because the electric field is uniform.

    B) increases because the charge moves along the electric field.

    C) decreases because the charge moves along the electric field.

    D) decreases because the charge moves opposite to the electric field.

    Correct Answer: C

    Solution :

    Option [c] is correct. Explanation: As we know that, an equipotential surface is always perpendicular to the direction of electric field. Positive charge experiences the force in the direction of electric field. When a positive charge is released from rest in uniform electric field, its velocity increases in the direction of electric field. So K.E. increases, and the P.E. decreases due to law of conservation of energy.
