The equation for the electric potential surrounding a point charge (or a spherical object with uniform charge distribution) is:
V=kqr
In this equation, k is the Coulomb constant, q is the amount of charge, and r is the distance from the point charge to the location where we want to know the electric potential (or the distance from the center of the sphere to the location where we want to know the electric potential).
Electric potential is NOT a vector quantity, but can be positive or negative.
The only way we could possibly have a zero potential as a result of two charged objects is if we had one positively charged object and one negatively charged object.
In this case, both objects are positively charged, leading to a positive potential everywhere, except at an infinite distance from the objects
so the correct answer is option "E"
