Question
Three long, straight and parallel wires carrying currents are arranged as shown in the figure. The wire C which carries a current of 5.0 amp is so placed that it experiences no force. The distance of wire C from wire D is then
- 9 cm
- 7 cm
- 5 cm
- 3 cm
The correct answer is: 9 cm
For no force on wire C, force on wire C due to wire D= force on wire C due to wire B
