Dimensions of Permeability of Free Space – Rankers Physics

Dimensions: Practice Problem & Solution

The dimensional formula of permeability of free space \(\mu_0\) is [1991]
\(MLT^{-2}A^{-2}\)
\(M^0L^{-1}T\)
\(M^0LT^{-1}A^2\)
None of these

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Dimensions. Understanding the underlying formula is key to arriving at the correct answer below:

From Ampere's law, the dimensions of permeability of free space \(\mu_0\) are derived as \(MLT^{-2}A^{-2}\).
