Two infinitely long parallel conductors in vacuum any separated 1 metre between centers >then a current of 1 ampere flows the. uk each conductor, produce on each other a force of_________________?
Correct answer: D. 2x 1(T7 N/m)
- A. 2 x 1(T2 N/m)
- B. 2 x KT3 N/m
- C. 2 x 10″5 N/m
- D. 2x 1(T7 N/m)
Explanation
For two parallel conductors, force per metre is F/L = μ₀I₁I₂/(2πd). With both currents 1 A and spacing 1 m, this becomes 2 × 10⁻⁷ N/m.
