A capacitor is made of a flat plate of area A and B second plate having a stair-like structure as shown in. The area of each stair is `A//3`, and the height is
d. Find the capacitance of this arrangement.
.

A

`(epsilon_(0)A(3d^2+6bd+2b^2))/(3d(d+b)(d+2b))`

B

`(epsilon_(0)A(3d^2-6bd-2b^2))/(3d(d-b)(d-2b))`

C

`(epsilon_(0)A(2d^2-bd-2b^2))/(3d(d+b)(d+2b))`

D

`(epsilon_(0)A(d^2-bd-b^2))/(3d(d+b)(d+b))`
