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

  • question_answer
    The intensity of an electric field inside a capacitor is E. The work done to move a charge g in a closed rectangular loop is:

    A) \[E\left( 2a+2b \right)\]

    B) \[E\left( 2a \right)\]

    C) Ea

    D) zero

    Correct Answer: D

    Solution :

    (d) zero Work done in moving a charge q from o to b = 0 Work done in moving a charge q from c to d = 0 This is because electric field is perpendicular to the displacement. Now, work done from b to c = - work done from d to a \[\therefore \] Total work done = 0
