A) \[\frac{2{{\varepsilon }_{0}}A}{d}\]
B) \[\frac{3{{\varepsilon }_{0}}A}{d}\]
C) \[\frac{3{{\varepsilon }_{0}}A}{2d}\]
D) \[\frac{{{\varepsilon }_{0}}A}{d}\]
Correct Answer: B
Solution :
The given arrangement is equivalent to the parallel combination of three identical capacitors. Hence equivalent capacitance \[=3C=3\frac{{{\varepsilon }_{0}}A}{d}\]
