    An uncharged sphere of metal is placed inside a charged parallel plate capacitor. The lines of force will look like:

    A)      

    B)

    C)  

    D)

    Correct Answer: A

    Solution :

    When metal sphere is placed inside a charged parallel plate capacitor, the electric lines of force will not enter the metallic conductor as \[E=0\] inside a charged conductor. Moreover, the surface of a charged conductor is an equipotential surface and hence, electric lines of force are always perpendicular to equipotential surface.
