$A$ capacitor is charged by using a battery which is then disconnected. $A$ dielectric slab is introduced between the plates which results in
- Aincrease in the potential difference across the plates and reduction in stored energy but no change in the charge on the plates
- Bdecrease in the potential difference across the plates and reduction in the stored energy but no change in the charge on the plates
- Creduction of charge on the plates and increase of potential difference across the plates
- Dincrease in stored energy but no change in potential difference across the plates

View SolutionTwo identical capacitors $A$ and $B$ are connected in series to a battery of $E$.$M$.$F$. $E$. Capacitor $B$ contains a slab of dielectric constant $K$. $Q_A$ and $Q_B$ are the charges stored in $A$ and $B$. When the dielectric slab is removed,the corresponding charges are $Q_A^{\prime}$ and $Q_B^{\prime}$. Then:
The parallel combination of two air-filled parallel plate capacitors of capacitance $C$ and $nC$ is connected to a battery of voltage $V$. When the capacitors are fully charged,the battery is removed,and after that,a dielectric material of dielectric constant $K$ is placed between the two plates of the first capacitor. The new potential difference of the combined system is
