Answer:
N
N
Explanation:
= 1 A
= 4 A
= distance between the two wire = 5 m
= Force per unit length acting between the two wires
Force per unit length acting between the two wires is given as


N
= distance of each wire from the midpoint = 2.5 m
Magnetic field midway between the two wires is given as
