Velocity of light is equal to

Options

  1. A₀ ₀
  2. B₀ / ₀
  3. C₀ / ₀
  4. D1 ₀ ₀ .

Correct answer

D. 1 ₀ ₀ .

Step-by-step solution

Relation for velocity of light (c)= 1 ₀ ₀ (where ₀= permittivity constant equal to 8.85 10⁻¹² ~F / m and ₀= permeability constant equal to 1.26 10⁻⁶ H / m . Numerically velocity of light (c)= 1 ₀ ₀ = 1 (8.85 10⁻¹² ) (1.26 10⁻⁶ ) 3 10^8 ~m / s .
