Circuits $(a)$ and $(b)$ have charged capacitors with capacitances $C, 2C$ and $3C$ as shown,with an open switch $S$. When the switch is closed,determine the direction of charge flow for each circuit.

• A
  In both $(a)$ and $(b)$,charge flows from $L$ to $R$.
• B
  In $(a)$,no charge flows,but in $(b)$,charge flows from $R$ to $L$.
• C
  In $(a)$,no charge flows,but in $(b)$,charge flows from $L$ to $R$.
• D
  In $(a)$,charge flows from $R$ to $L$,and in $(b)$,charge flows from $L$ to $R$.
