Three identical large plates are fixed at separation of d from each other as shown in figure. The area of each plate is A. Plate 1 is given charge `+Q` while plates 2 and 3 are neutral and are connected to each other through coil of inductances L and switch S. If resistance of all connected wires is neglected the maximum current flow through coil after closing switch is (`C=epsilone_0 A/d`) (neglect fringe effect)

Options

A. `(Q_(0))/(sqrt(LC))`
B. `(Q_(0))/(sqrt(2LC))`
C. `(2Q_(0))/(sqrt(LC))`
D. `(Q_(0))/(2sqrt(LC))`

Explanation

`((Q/2)^(2))/(2C)=1/2 Li_(0)^(2)`
`rArr I_(0)=Q/(2sqrt(LC))`
