A parallel plate capacitor with square plates is filled with four dielectrics of dielectric constants $\displaystyle \mathrm{K}_1, \mathrm{~K}_2, \mathrm{~K}_3, \mathrm{~K}_4$ arranged as shown in the figure. The effective dielectric constant K will be :
Official answer
(2)
$\displaystyle K=\frac{\left(K_1+K_3\right)\left(K_2+K_4\right)}{K_1+K_2+K_3+K_4}$
