Hint : Dielectric constant is also called relative permeability, refers to how easily an element can be polarized by applying an electric field to an instrument. Centimeter gram second is also known as the CGS system.
Complete step by step solution:
The degree to which a medium can polarize in response to an electric field is determined by its permittivity.
In Cgs units, ε is unitless. In SI units, Far is in units of Farads / meter. This highlights the fundamental differences between the two measures of permeability in different unit systems.
Hence, option A is correct.
Additional Information: Permittivity and dielectric constant are two terms that are central to capacitor technology. Often conversations with capacitors are heard using separate dielectrics. All common names for electrolytic capacitors, ceramic capacitors, paper, tantalum, capacitors, and capacitors, refer to the dioxide used.
The dielectric components provide insulation between the capacitor plates and in addition it determines many of the properties of the capacitor. This capacitance is achieved in constant quantities, whether the temperature constant is polarized or not. These and many other properties are controlled by the dielectric material used - many properties are managed only by the dielectric constant.
Note: Absolute permeability: Absolute permeability is defined as the measure of permeability in a vacuum and how much resistivity it encounters when creating an electric field in a vacuum. Absolute permeability is normally symbolized by perm0. Permeability of free space - a vacuum - is equal to about 8.85 x 10-12 farads per m (F / m)
Relative permeability is the ratio of the permeability of a substance to the permeability of space or emptiness.
