Explanation / Answer

here,

the current in the motor wire , I1 = 375 A

the current in the headlight wire , I2 = 4.6 A

let the sepration between the wires be r

force per unit length , F = u0 * I1 * I2 /(2*pi*r)

4.5 * 10^-3 = 1.26 * 10^-6 * 375 * 4.6 /( 2 * pi * r)

solving for r

r = 0.077 m = 7.7 * 10^-2 m

the sepration between the wires is 7.7 * 10^-2 m
