    The plates of a parallel plate capacitor are not. exactly parallel. The surface charge density

    A)  is lower at the closer end

    B)  will not be uniform

    C)  each plate will have the same potential at every point

    D)  Both [b] and [c]

    Correct Answer: D

    Solution :

     Being a conductor, each plate has the same potential at each point. As\[E\propto \sigma ,\]so surface charge density a is higher at the closer end because electric field being the conductor gradient of potential is highest where the plates are closest to each other.
