NEET Physics Potential Difference MCQ Question
When a dielectric slab of dielectric constant K is inserted between the plates of a parallel-plate capacitor, reducing the electric field to E = E0/K, what happens to the potential difference across the capacitor?
It decreases by a factor of K.
It increases by a factor of K.
It remains the same.
It becomes zero.
Correct Answer
Detailed Explanation
When a dielectric is inserted, the electric field is reduced, leading to a decrease in potential difference by the same factor, as described in the NCERT context.
