Physics - Capacitor Question with Solution | TestHub

There are six plates of equal area A and separation between the plates is $\mathrm{d}(\mathrm{d}\ll \mathrm{A})$ are arranged as shown in figure. The equivalent capacitance between points 2 and 5, is $\alpha \frac{{ϵ}_0\mathrm{A}}{\mathrm{d}}$. Then find the value of $\alpha$.
