In the figure a capacitor is filled with dielectrics. The resultant capacitance is [UPSEAT 2001]

\[\frac{2{{\varepsilon }_{0}}A}{d}\,\left[ \frac{1}{{{k}_{1}}}+\frac{1}{{{k}_{2}}}+\frac{1}{{{k}_{3}}} \right]\]

\[\frac{{{\varepsilon }_{0}}A}{d}\,\left[ \frac{1}{{{k}_{1}}}+\frac{1}{{{k}_{2}}}+\frac{1}{{{k}_{3}}} \right]\]

\[\frac{2{{\varepsilon }_{0}}A}{d}\,\left[ {{k}_{1}}+{{k}_{2}}+{{k}_{3}} \right]\]
