The diagram shows an arrangement of identical metal plates placed parallel to each other and the variation of potential between the paltes by dotted lilne. Using the details given in diagram, the equivalent capacitance connected across the plate No. `2` and plate No. `4` is
(Separation between the consecutive plates `=L`, area of each plate `=A`)

Options

A. `(3epsilon_(0)A)/L`
B. `(3epsilon_(0)A)/(4L)`
C. `(6epsilon_(0)A)/(5L)`
D. `(epsilon_(0)A)/L`

Answer

C

Explanation

Circuit can be redrawn as
`C_(eq)=(6C)/5=(6epsilon_(0)A)/(5L)`
