Which of the following physical quantities have the same dimensions?

Options:

Answer:

Solution:

Electric displacement
$\vec{D} = ϵ_{0} \vec{E}$
$[D] = [ϵ_{0} E] = [ϵ_{0} \frac{σ}{ϵ_{0}}]$
$[D] = [σ]$
And surface charge density $= σ$ .
Thus, electric displacement $(D)$ and surface charge density have same dimension.
