        A parallel plate capacitor is connected across a 2 V battery and charged. The battery is then disconnected and a glass slab is introduced between plates. Which of the following pairs of quantities decrease?

    A)  Charge and potential difference

    B)  Potential difference and energy stored

    C)  Energy stored and capacitance

    D)  Capacitance and charge

    Correct Answer: B

    Solution :

                    When battery is disconnected charge remains constants-On introducing glass slab capacity increases. Potential difference and energy stored decreases.
