Two parallel conductors each of 0.50-m length, separated by 5.0 *10 ^- ³ m and carrying 3.0 A in the same direction, will experience what type and magnitude of mutual force? (magnetic permeability in empty space µ₀ = 4 $\pi$*10 ^- ⁷ T.m/A) A) attractive, 1.8 * 10 ^- ⁴ N B) repulsive, 1.8 /10 ^- ⁴ N C) repulsive, 0.60 *10 ^- ⁴ N D) attractive, 0.06 *10 ^- ⁴ N

The force between two parallel conductors carrying current in the same direction is attractive. The magnitude of the force per unit length is given by the formula F/L = (µ₀ * I₁ * I₂) / (2π * d). Substituting the given values, the force is calculated to be 1.8 x 10⁻⁴ N, which matches option A.
