Consider a high-power laser, operating at a wavelength of 1.6μm, which puts out 10kJ in 0.2ns. The beam is focused on an area of diameter 0.5 mm. What is the RMS electric field strength in V/m unit?​

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.

Ibelieve the answer is d. macula  hope my answer has you : )
