Answer:
F = 0.018 N
Explanation:
Magnetic force between two parallel current carrying wires is given by
[tex]F = \frac{\mu_0 i_1 i_2 L}{2\pi d}[/tex]
here we know that
[tex]i_1 = 34 A[/tex]
[tex]i_2 = 69 A[/tex]
d = 15 cm
L = 5.9 m
now from above formula we can say
[tex]F = \frac{(4\pi \times 10^{-7})(34 A)(69 A)5.9}{2\pi (0.15)}[/tex]
now the force between two wires is given as
[tex]F = 0.018 N[/tex]
