Question

Write down unit and dimention of permittivity of free space

Answer 1

the unit is farad per metre and dimention is ( charge )2 is the permittivity of free spaace

Answer 2

The S.I unit for the constant, permittivity is Farad / meter

EXPLANATION:

The constant of a free space known as permittivity and has a value equal to $8.85 \times 10^{-12}$ farad per meter. The dimension is $\left[M^{-1} L^{-3} T^{4} A^{2}\right]$

Then, the “permittivity of free space” is also defined as a proportionality constant present between the ‘dielectric constant’ of a material and the ‘electric field intensity’. The permittivity is denoted by $\varepsilon_{0}$.The lowest value possible for this is that of vacuum.
