A force F = 2i 3j + k acts at the point (1, 5, 2). Find the torque due to F (a) about the origin; (b) about the y axis; (c) about the line x/2 = y/1 = z/(2)

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.

I'm pretty sure the answer is c
