What is the dimensional formula of electric permittivity of free space?

IF in_0 is electric permittivity of free space and E is electric field, then show that in_0E^2 has the dimensions of pressure.

If e, in_0, h and c respectively represent electric, charge, permittivity of free space, Planck's constant and speed of light then (e^2)/(in_0 hc) has the dimensions of a) angle b) relative density c) strain d) current

(i) mu=(c)/(v_m)=(vlambda)/(vlambda_m) where c: speed of light in vacuum v_m: speed of light in medium lambda: wavelength in vacuum lambda_m : wavelength in medium upsilon: frequency of light (ii) mu=((epsilonmu)/(epsilon_0mu_0))^(1/2) where epsilon: electric permittivity in free space epsilon: electric permittivity in medium mu_0: magnetic permeability in free space mu: magnetic permeability in medium (iii) mu=A+B/lambda^2 , where A and B are constants (iv) In case of VIBGYOR, wavelength increases from violet to red, refractive index decreases from violet to red. Wavelength for red-colour is maximum whereas refractive index is maximum for violet colour.

SI unit of in_(0) (permittivity of free space) is:

The dimension of (1/2)ε0E^2 where ∈0 is permittivity of free space and E is electric field,is
