Final answer:
The electric field used in the relation P = εoχeE is the applied electric field (E0).
Step-by-step explanation:
The electric field used in the relation P = εoχeE is the applied electric field (E0). The relation describes the polarization of a material when subjected to an external electric field. The polarization (P) is directly proportional to the applied electric field (E0) and the electric susceptibility of the material (χe).
An electric field is a fundamental concept in physics that describes the influence that charged particles (such as electrons and protons) exert on each other. It is a vector field, meaning it has both magnitude and direction, and it represents the force experienced by a positive test charge at a given point in space due to the presence of other charges.
Units: The SI unit of the electric field is volts per meter (V/m).
Superposition Principle: The electric field due to multiple charges can be found by adding the electric fields produced by each charge. This principle allows for the calculation of the net electric field in a given region.
Relation to Voltage: The electric field is related to the voltage (
