NEET Physics Potential Difference MCQ Question
Which of the following statements about potential difference is correct?
The potential difference between two points is the work done per unit charge in bringing a charge from one point to another.
Potential difference can be negative if the initial point has a higher electric potential than the final point.
The potential difference is always directly proportional to the magnitude of the electric field between two points.
Potential difference does not depend on the path taken between two points in an electric field.
Correct Answer
Detailed Explanation
Statement A accurately defines potential difference as the work done per unit charge, as stated in the context. Statement B is misleading, as potential difference can be negative if the final point has a higher potential. Statement C is incorrect since potential difference is related but not always directly proportional to electric field magnitude. Statement D is correct, but A is the best definition.
