Four identical plates $$1, 2, 3,$$ and $$4$$ are placed parallel to each other at equal distance as shown in the figure. Plates $$1$$ and $$4$$ are joined together and the space between $$2$$ and $$3$$ is filled with a dielectric of dielectric constant $$k = 2$$. The capacitance of the system between $$1$$ and $$3$$ & $$2$$ and $$4$$ are $$C_1$$ and $$C_2$$ respectively. The ratio $$C_1/C_2$$ is :
