Physics · Electric flux, Gauss's law and its applications to find field due to infinitely long uniformly charged straight wire, uniformly charged infinite plane sheet and uniformly charged thin spherical shell
The Sl unit of electric flux density is
The Sl unit of electric flux density is
- A. \( N / C \)
- B. \( N m^{2} / C \)
- C. \( N m / C \)
- D. \( N m^{2} \)
Step-by-step solution
Electric flux density is defined as electric flux per unit area. Electric flux has SI unit N·m²/C, so dividing by area (m²) yields N/C, which is the unit of electric field.
