A) \[\frac{{{\varepsilon }_{0}}A}{t}\left( {{k}_{1}}+{{k}_{2}} \right)\]
B) \[\frac{{{\varepsilon }_{0}}A}{t}.\frac{{{k}_{1}}+{{k}_{2}}}{2}\]
C) \[\frac{2{{\varepsilon }_{0}}A}{t}\left( {{k}_{1}}+{{k}_{2}} \right)\]
D) \[\frac{{{\varepsilon }_{0}}A}{t}.\frac{{{k}_{1}}-{{k}_{2}}}{2}\]
Correct Answer: B
Solution :
[b] The two capacitors are in parallel so \[C=\frac{{{\varepsilon }_{0}}A}{t\times 2}\left( {{k}_{1}}+{{k}_{2}} \right)\]
