Question

One Ampere is the current which when flowing through each of the two parallel uniform long linear conductors placed in free space at a distance of one meter from each other will attract or repel each other with a force of

• A. 2 × 10^-7 N/m
• B. 2 × 10^-5 N/m
• C. 2 × 10^-3 N/m
• D. 2 × 10^-9 N/m

Answer 1

The correct option is A

2 × 10^-7 N/m

One Ampere is the current which when flowing through each of the two parallel uniform long linear conductors placed in free space at a distance of one meter from each other will attract or repel each other with a force of 2 × 10^-7 N/m.
