A) both V and E increase
B) both V and E decrease
C) V decreases, E increases
D) V increases, E decreases
Correct Answer: B
Solution :
When the gap between the plates is completely filled with dielectric of dielectric constant K, then potential is \[V=\frac{Qd}{A{{\varepsilon }_{0}}K}\] (i) and electric field is \[E=\frac{Q}{A{{\varepsilon }_{0}}K}\] (ii) From equations (i) and (ii), both electric field and potential decrease.You need to login to perform this action.
