Final answer:
The question is about calculating the magnetic force between two wires carrying electrical currents, which requires principles from Physics. It employs the meter, a fundamental unit of length in the SI system, and relates to electromagnetism. So, the best answer is e, none of the above.
Step-by-step explanation:
The subject question pertains to the magnetic force between two long, straight and parallel wires carrying currents. When two parallel wires carry currents in opposite directions, they exert a magnetic repulsive force on each other, while currents in the same direction result in an attractive force.
Using Ampère's law and the Biot-Savart law, we can calculate these forces.
These calculations involve understanding the principles of electromagnetism, a fundamental part of Physics. When discussing units of measurement, the meter (m) is a fundamental unit of length in the International System of Units (SI).
The definition of a meter has evolved to be based on the distance light travels in a vacuum in a precise fraction of a second.
So, the best answer is e, none of the above.
