A parallel plate capacitor is filled up by a substance of\[{{t}_{1}}\] thickness of dielectric constant \[{{K}_{1}}\] and other substance of \[{{t}_{2}}\] thickness of dielectric constant \[{{K}_{2.}}\] The capacity of this capacitor will be

A) \[{{\varepsilon }_{0}}A/\left( \frac{{{t}_{1}}}{{{K}_{1}}}+\frac{{{t}_{2}}}{{{K}_{2}}} \right)\]          

B) \[{{\varepsilon }_{0}}A/\left( \frac{{{K}_{1}}}{{{K}_{2}}}+\frac{{{K}_{2}}}{{{t}_{2}}} \right)\]

C) \[{{\varepsilon }_{0}}A/\left( \frac{{{t}_{1}}}{{{K}_{2}}}+\frac{{{t}_{2}}}{{{K}_{1}}} \right)\]          

D) \[{{\varepsilon }_{0}}A/\left( \frac{{{K}_{2}}}{{{t}_{1}}}+\frac{{{K}_{1}}}{{{t}_{2}}} \right)\]
