12th Class Physics Electrostatics & Capacitance Question Bank MCQ - Electrostatic Potential and Capacitance

  • question_answer
    In a region of constant potential:

    A) the electric field is uniform  

    B) the electric field is zero

    C) there can be no charge inside the region

    D) Both (b) and (c) are correct

    Correct Answer: D

    Solution :

    (d) Both (b) and (c) are correct In a region of constant potential \[E=-\frac{dV}{dr}=0\]                          (\[\because \]V= constant) i.e., electric field is zero, so there can be no charge inside the region.
