The cross-sectional area of a conductive wire is 1.3×10⁻¹¹m². Assuming that the wire contains charged particles with a number density of 1.8×10²⁴ particles /m³, and each of these particles carries a charge of +, what is the drift speed of these charged particles (measured in m ) when an electric current of 1×10⁻⁴ is observed in the wire due to the motion of these particles?
