Q. A capacitor of capacitance is connected to a battery of emf . After full charging a dielectric of same size as that of capacitor and dielectric constant is inserted. Then

KCET KCET 2022 Report Error

A

Electric field between the plates of capacitor remains same

B

charge on capacitor increases to 2 KCE

C

Energy stored in capacitor decreases

D

Electric field between plates of capacitor increases

Solution:

After inserting the dielectric the resultant electric field decreases, but the electric field between plates of capacitor remains same
