alleryEquipotential surfaces are everywhere:
AParallel to the field lines
BInclined at 45° to field lines
CPerpendicular to the field lines
DConcentric with charges only
Answer & Solution
Correct answer: C. Perpendicular to the field lines
1. dW = qE·dr along an equipotential = 0 ⇒ E ⊥ displacement on the surface.
2. So field lines cross equipotentials at 90° everywhere.
3. No work is done in moving a charge along an equipotential.
