In addition to the distance between two particles what other factor determines the magnitude of the electric force between the particles

Ithink the answers is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
