Equipotential surfaces around a point charge are:
ACubes
BCylinders
CConcentric spheres
DPlanes
Answer & Solution
Correct answer: C. Concentric spheres
V = kq/r = constant when r = constant — equation of a sphere centered at the charge. So equipotentials are concentric spheres. E is everywhere perpendicular to these spheres.
