Two point charges are arranged as shown. The left charge is +1 C and the right charge is –1 C. Which direction would a positive charge (+) move if it was placed on the right of the right charge?

No because a circle or pie graph usually shows percentages you'd need a line graph

The rearrangement of particles in a physical change. hope this

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.
