DNo unit
Answer:
D. No unit
Read Explanation:
Definition: Relative permittivity, also known as the dielectric constant, is defined as the ratio of the permittivity of a substance (ε) to the permittivity of free space (ε₀).
Mathematical Formula: It is represented as εᵣ = ε / ε₀.
Unitless Property: Since relative permittivity is a ratio of two quantities with the same physical dimensions (both being permittivity measured in Farads per meter, F/m), the units cancel out. Therefore, it is a dimensionless and unitless physical quantity.
Characteristics: Because it is a ratio, its value is independent of the system of units being used (SI, CGS, etc.).
