A capacitor is made of a flat plate of area $A$ and a second plate having a stair-like structure as shown in the diagram. The capacitance of the arrangement is-

Options:

Answer:

Solution:

All the steps of stair makes three parellel capacitors.

$C_{e q} = C_{1} + C_{2} + C_{3}$

$= \frac{ε_{0} A}{3 d} + \frac{ε_{0} A}{3 \times 2 d} + \frac{ε_{0} A}{3 \times 3 d} = \frac{11 ε_{0} A}{18 d}$
