A) Both V and E increase
B) Both V and E decrease
C) V decreases, F increases
D) V increases, £ decreases
Correct Answer: B
Solution :
(b) Both V and E decrease When the gap between the plates is completely filled with dielectric of dielectric constant K, then potential is \[V=\frac{Qd}{A{{\varepsilon }_{0}}K}\] (1) And electric field is \[E=\frac{Q}{A{{\varepsilon }_{0}}K}\] (2) From eqs. (1) and (2), both electric field and potential decrease.You need to login to perform this action.
