Equipotential at a great distance from a collection of charges whose total sum is not zero are approximately

Answer»

spheres
planes
PARABOLOIDS
ellipsoids

Solution :The collection of charges can be considered as a single point charge. Because, sum of their charges is not zero.
The electric potential due to point charge is`V(R) = (kq)/(r)` . It MEANS electric potential due to point charge is samefor all equidistant points which is known as equipotential SURFACES and it is three dimensional spheres.
