(i) increase in the value of charge on \[{{C}_{1}}\] (ii) increase in the value of charge on \[{{C}_{2}}\] (iii) increase in the value of potential difference across the plates of \[{{C}_{1}}\] (iv) decrease in the value of potential difference across the plates of \[{{C}_{3}}\] Which of the above is true?
A) (i), (ii), (iii) and (iv)
B) (ii) only
C) (ii) and (iv)
D) (i) and (iv)
Correct Answer: B
Solution :
If a dielectric medium of dielectric constant fc is filled completely between the plates then capacitance increases by fc times \[C=\frac{k{{\varepsilon }_{0}}A}{d}\] \[\Rightarrow \] \[C=kQ\]and charge \[Q=kQ\] \[\therefore \] Increase in the value of charge on \[{{C}_{2}}\].
