# Find the equivalent capacitances of the capacitors shown in figure. The plate area is A and the separation between the plates is d. Different dielectric slabs in a particular part of the figure are of the same thickness and the entire gap between the plates is filled with the dielectric slabs.

$\large\frac{3 \in_0 A k_1k_2k_3}{d(k_1k_2+k_2k_3+k_2k_3)}$
