12th Class Physics Electric Charges and Fields Question Bank Assertion And Reason (MCQs) - Electric Charges and Fields

  • question_answer
     
    ASSERTION: The electric lines of forces diverge from a positive charge and converge at a negative charge.
    REASON: A charged particle free to move in an electric field always moves along an electric line of force.

    A) If both assertion and reason are true and reason is the correct explanation of assertion.

    B) If both assertion and reason are true and reason is not the correct explanation of assertion.

    C) If assertion is true but reason is false.

    D) If both assertion and reason are false.

    E) If assertion is false but reason is true.

    Correct Answer: C

    Solution :

    If the charged particle is initially at rest in an electric field, it will move along the electric line of force. But when the initial velocity of charged particle makes some angle with the line of force then resultant path is not along the line of force. Because electric line of force may not coincide with the line of velocity of the charge.
