A parallel plate capacitor has capacitance C. If it is equally filled with parallel layers of materials of dielectric constants \[{{K}_{\text{1}}}\] and \[{{K}_{\text{2}}}\] its capacity becomes \[{{C}_{\text{1}}}\]. The ratio of \[{{C}_{\text{1}}}\] to C is [MP PMT 2001]

\[\frac{{{K}_{1}}{{K}_{2}}}{{{K}_{1}}-{{K}_{2}}}\]

\[\frac{{{K}_{1}}+{{K}_{2}}}{{{K}_{1}}{{K}_{2}}}\]

\[\frac{2{{K}_{1}}{{K}_{2}}}{{{K}_{1}}+{{K}_{2}}}\]
