Answer 1

The unit of permittivity of free space ϵ0 is :-

The unit of permittivity of free space ϵ0 is :-The SI unit for permittivity is farad per meter (F/m or F. ... The lowest possible permittivity is that of a vacuum. Vacuum permittivity, sometimes called the electric constant, is represented by ε0and has a value of approximately 8.85×10−12 F/m

Answer 2

The permeability of free space, μ0, is a physical constant used often in electromagnetism. It is defined to have the exact value of 4π x 10-7 N/A2 (newtons per ampere squared).[1] It is connected to the energy stored in a magnetic field, see Hyperphysics for specific equations.
