NEET 2017 Physics Equipotential Surfaces MCQ Question
The diagrams below show regions of equipotentials. A positive charge is moved from A to B in each diagram. Maximum work is required to move q in figure (c).
In all the four cases the work done is the same
Minimum work is required to move qq in fig (I)
Maximum work is required to move qq in fig (II)
Maximum work is required to move qq in fig (II)
Correct Answer
Detailed Explanation
Work done is maximum when the potential difference is maximum. In figure (c), the potential difference between points A and B is the greatest.
