The unit of the electric field is:
Correct answer: D. All of the above
- A. N/C
- B. V/m
- C. J/C.m
- D. All of the above
Explanation
The units of the electric field in the SI system are newtons per coulomb (N/C), or volts per meter (V/m); in terms of the SI base units they are kg⋅m⋅s−3⋅A−1. Since all options are valid, D is the answer.

About Electric Field Intensity
Electric field intensity is the force acting per unit positive test charge, with direction set by the force on that charge. Work includes fields of point charges, vector superposition, field lines and the relation between field and electric potential. Field intensity must be distinguished from electric force and potential.
