The unit of electric field is not equivalent to
Correct answer: D. J/C.m
- A. N/C
- B. V/m
- C. J/C
- D. J/C.m
Explanation
The correct unit of electric field is newtons per coulomb (N/C) or volts per meter (V/m). The option (c) is incorrect as it represents energy per unit charge, not electric field.E = F / qUnits of the involved quantities:Force (F): Measured in Newtons (N)Charge (q): Measured in Coulombs (C)so E=N/C also E= V/d so volt/meter is also a unit of electric field.Though J/C is not the direct unit of the electric field, it represents the energy density associated with the electric field. Higher values of J/C indicate a stronger electric field that stores more energy per unit volume.Incorrect options: (a) N/C is the correct unit of electric field.(b) V/m is also a correct unit of electric field.(d) J/C represents the electric field density.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
