A parallel plate capacitor of capacitance \( C \) is connected to a battery till it is fully charged. A dielectric slab is inserted between the plates. Match the columns of given that battery is disconnected before slab insertion. (All entries are related to capacitor) \begin{tabular}{|l|l|} \hline Column I & Column II \\ \hline A) Capacitance & P) Zero \\ \hline B) Potential difference & Q) Increases \\ \hline C) Electric field & R) Decreases \\ \hline D) Energy stored & S) Increases first then decrease \\ \hline & T) Remains same \\ \hline & U) Decreases first then increase \\ \hline \end{tabular} \( A \rightarrow Q, B \rightarrow R, C \rightarrow \cup, D \rightarrow R \) \( A \rightarrow Q, B \rightarrow S, C \rightarrow U, D \rightarrow T \) \( A \rightarrow Q, B \rightarrow R, C \rightarrow R, D \rightarrow R \) \( A \rightarrow T, B \rightarrow U, C \rightarrow T, D \rightarrow R \)
