If `e, in_(0) h` and `c` respectively present electric charge, permittivitty of free space, Planck's constant and speed of light then `(e^(2))/(in_(0) hc)` has the dimensions of

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

If e, E_0, h and C respectively represents electronic change, permittively of free space, planks constant and speed of light then (e^2)/(E_0 hC) has the dimensions of A) angle " " B) relative density C) strain " " D) current

If e, E_0, h and C respectively represents electronic change, permittively of free space, planks constant and speed of light then (e^2)/(E_0 hC) has the dimensions of A) angle " " B) relative density C) strain " " D) current

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

If e is the electronic charge, c is the speed of light in free space and h is Planck's constant, the quantity (1)/(4pi epsilon_(0)) (|e|^(2))/(hc) has dimensions of :

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.
