An equipotential surface is a surface on which
AThe charge density is uniform
BThe work done by external agents is maximum
CThe electric field is uniform but the potential varies
DThe potential has the same value at every point
Answer & Solution
Correct answer: D. The potential has the same value at every point
By definition, an equipotential surface is a locus of points all at the same potential V. Consequently, no work is done in moving a charge along it.
