12th Class Physics Electric Charges and Fields Question Bank Case Based (MCQs) - Electric Charges and Fields

  • question_answer
    Consider a region inside which, there are various types of charges but the total charge is zero. At points outside the region:

    A) the electric field is necessarily zero

    B) the electric field is due to the dipole moment of the charge distribution only

    C) the dominant electric field is inversely proportional to \[{{r}^{3}}\]for larger r (distance from origin)

    D) the work done to move a charged particle along a closed path, away from the region will not be zero

    Correct Answer: C

    Solution :

    (c) the dominant electric field is inversely proportional to \[{{r}^{3}}\], for large r (distance from origin)
