The unit of permittivity of free space ₀ , is:

Options

  1. Acoulomb/newton-metre
  2. Bnewton-metre ^2 / coulomb ^2
  3. Ccoulomb ^2 / newton-metre ^2
  4. Dcoulomb ^2 / (newton-metre) ^2

Correct answer

C. coulomb ^2 / newton-metre ^2

Step-by-step solution

We know that aligned & F= 1 4 ₀ q^2 r^2 & ₀= 1 4 a^2 Fr r^2 = C ^2 ~N - m ^2 & aligned
