Equipotential SurfacesHardQuestion 31455
Question
No two equipotential surfaces can intersect because:
- AThey are all parallel
- BAt the intersection, there would be two values of potential at one point — impossibleCorrect
- CCharge cannot exist between them
- DElectric field is zero between them
Correct answer
At the intersection, there would be two values of potential at one point — impossible
Explanation
Potential V is a single-valued function at each point. Intersection of two equipotentials of different V values would mean two potentials at one point — a contradiction.
