Three large identical conducting plates of area A are closely placed parallel to each other as shown (the area A is perpendicular to plane of diagram). The net charge on left, middle and right plates are $Q_{L}, Q_{M} a n d Q_{R}$ respectively. Three infinitely large parallel surfaces $S_{L}, S_{M} a n d S_{R}$ are drawn passing through middle of each plate such that surfaces are perpendicular to plane of diagram as shown. Then pick up the correct option(s).

Detailed Solution

Since electric field on plate at surface $S_{L}$ is zero, net charge on left side of $S_{L}$ is equal to net charge on right side of $S_{L} .$ Further net charge between any two dotted surfaces (out of $S_{L}, S_{M} a n d S_{R}$ ) is zero from Gauss theorem
