Questions
A B C is a current carrying conductor carrying a current i = 2A. If length of the segment Ab is m, then what should be the length of BC . So that net force on the conductor ABC becomes zero?
detailed solution
Correct option is A
F→=i le→×B→Where le = Ac = equivalent length. It is evident that F→ is zero when le→ and B→ are parallel (as shown in the figure).∴BC=AB/cos300=3332 m =6 mTalk to our academic expert!
