The unit of εr
Correct answer: D. no unit
- A. Nm-1 A-1
- B. N-1m1C²
- C. Nm²C²
- D. no unit
Explanation
εr is the relative permittivity. It is the ratio is permittivity of the substance and the permittivity of free space.εr= ε / εoHence, it has no unit

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.
