NEET Physics Potential Difference MCQ Question
What happens to the electric field in a parallel-plate capacitor when a dielectric is inserted?
The electric field decreases by a factor of the dielectric constant K.
The electric field remains unchanged regardless of the dielectric.
The electric field increases as the dielectric is inserted.
The electric field becomes zero immediately after insertion.
Correct Answer
Detailed Explanation
When a dielectric is inserted into a parallel-plate capacitor, the electric field in the dielectric becomes E = E0/K, where E0 is the electric field without the dielectric. This indicates that the electric field decreases by a factor equal to the dielectric constant K.
