A) \[KC\]
B) \[(K+1)C\]
C) \[(K+1)C\text{/2}\]
D) \[(K-1)C\]
Correct Answer: C
Solution :
Initial capacitance of the capacitor, \[C=\frac{A{{\varepsilon }_{0}}}{d}\] ?.(i) Final capacitance \[C'={{C}_{1}}+{{C}_{2}}\] \[=\frac{\frac{A}{2}{{\varepsilon }_{0}}}{d}+\frac{K\frac{A}{2}{{\varepsilon }_{0}}}{d}\] \[=\frac{A{{\varepsilon }_{0}}}{2d}\,(1+K)\] \[=\frac{(1+K)}{2}C\]You need to login to perform this action.
