Considering the fact that electrostatic force is a conservative force, judge the following items to be true or false, explaining each one. I. Electrical Potential Energy is an absolute concept that does not depend on whether an electrostatic force is conservative. II. Only Electrical Potential Energy differences have physical relevance. III. Saying that a force is conservative is equivalent to saying that ∇×F=0 or ∮CF⋅dℓ⃗=0. IV. The electrostatic potential of a point charge is defined as the work (per unit charge) performed by an external agent to bring a charge from infinity to a position of interest.
