Question:

The dimensions of $(μ_0ε_0)^\frac{-1}{2}$

Options:

[$L^{−1}T$]

[$LT^{−1}$]

[$L^\frac{-1}{2}T^\frac{1}{2}$]

[$L^\frac{1}{2}T^\frac{-1}{2}$]

Correct Answer:

[$LT^{−1}$]

Explanation:

speed of light is c= $(μ_0ε_0)^−\frac{1}{2}$ so dimension of $(μ_0ε_0)^−\frac{1}{2}$ is same as dimension of speed of light. i.e [$LT^{−1}$]
