Electromagnetism

Step 1: Understanding the relationship between electric permittivity and magnetic permeability.
The electric permittivity and magnetic permeability are related through the speed of light in a vacuum: The speed of light has the dimensional formula .
Step 2: Dimensional analysis.
We are given that the dimensional unit of magnetic permeability is . Now, substituting into the equation , we can solve for the dimensional formula of .
Using dimensional analysis, we get the formula for electric permittivity as . Thus, the correct answer is
(C) .
