1.	Three identical parallel conducting plates A, B and C are placed as shown. Switches S1 and S2 are open and can connect A and C to earth when closed. +Q charge is given to B. Find the magnitude of charge flown through S1 when S1 is closed and S2 remains open.
Answer» Three identical parallel conducting plates $A, B$ and $C$ are placed as shown. Switches $S_{1}$ and $S_{2}$ are open and can connect $A$ and $C$ to earth when closed. $+ Q$ charge is given to $B$ . Find the magnitude of charge flown through $S_{1}$ when $S_{1}$ is closed and $S_{2}$ remains open.
