NEET Physics Potential Difference Assertion Reason Question
Assertion (A): The potential difference across a capacitor decreases when a dielectric is inserted between its plates. | Reason (R): The polarization of the dielectric reduces the effective electric field between the plates.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The insertion of a dielectric reduces the effective electric field, which in turn decreases the potential difference as described by the formula V = Ed.
