Dimensions of 1/μoεo, where symbols have their usual meaning

• Measurement

Dimensions of 1/μ_oε_o, where symbols have their usual meaning, are

1. [L²T^–2]
2. [LT^–1]
3. [L^–2T²]
4. [L^–1T]

Answer

Velocity of light in vacuum = 1/√(μ_oε_o)

[LT^-1] = [1/√(μ_oε_o)]

[L²T^-2] = [1/(μ_oε_o)]

The correct option is A.
