10. Which of the following is the correct definition of ampere?

The ampere is the value of that steady current which when maintained in each of the two very long, straight, parallel conductors of negligible cross-section, and placed one metre apart in vacuum, would produce on each of these conductors a force equal to 2 × 10⁷ N/m of length.

The ampere is the value of that steady current which when maintained in each of the two very long, straight, parallel conductors of negligible cross-section, and placed one centimetre apart in vacuum, would produce on each of these conductors a force equal to 2 × 10^–7 N/m of length.

The ampere is the value of that steady current which, when maintained in each of the two very long, straight, parallel conductors of negligible cross-section, and placed one metre apart in vacuum, would produce on each of these conductors a force equal to 2 × 10^–7 N/m of length.

The ampere is the value of that steady current which, when maintained in each of the two very long, straight, parallel conductors of negligible cross-section, and placed ten metre apart in vacuum, would produce on each of these conductors a force equal to 2 × 10^–7 N/m of length.
