Question
Two thin, long parallel wires separated by a distance ′d′ carry a current of ′i′ A in the same direction. They will
Options
A.attract each other with a force of μ0i2/(2πd)
B.repel each other with a force of μ0i2/(2πd)
C.attract each other with a force of μ0i2/(2πd2)
D.repel each other with a force of μ0i2/(2πd2)
Solution
Using the definition of force per unit length due to two long parallel wires carrying currents.
