Physics · Class 12 · CBSE — Moving Charges and Magnetism
Two long, straight, parallel conductors carry the same current and attract each other with a force F per unit length. If the current is doubled in each conductor and their separation is made half, the force per unit length becomes:
- \(\frac{{F}}{2}\)
- 2 F
- 4 F
- 8 F
Answer
(D) 8 F
