What type of energy store do two electric charges that attract or repel possess?

The correct answer is electrostatic energy store. Electric charges have the ability to interact with one another through the electric force, which can lead to attraction or repulsion. This interaction is due to the electrostatic force that arises from the presence of electric charges. When two charges of opposite polarity come close to each other, they possess potential energy in the form of electrostatic energy due to their positions relative to each other. If they are allowed to move, this stored energy can be converted into kinetic energy as the charges attract each other.

In contrast, magnetic energy pertains to magnetic fields and their interactions with magnetic materials, which is not relevant to electric charges. Chemical energy involves the stored energy within chemical bonds and is not applicable here either. Kinetic energy relates to the energy of motion, which would not be the primary focus when discussing the interaction between two electric charges at rest or at a distance. Thus, the presence of an electrostatic energy store is the key factor when considering the potential interactions of electric charges.
