Two point charges are located at two of the vertices of a right triangle, as shown in the Figure 16.4. If a third charge -2q is brought from infinity and placed at the third vertex, what will its
electric potential energy be? Use the following values: a = 0.16 m; b = 0.45 m, and q = 2.0 x 10-
C.

Definitely the indoraptor

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.
