The cross-sectional area of a conductive wire is 1.3Ć10ā»Ā¹Ā¹m². Assuming that the wire contains charged particles with a number density of 1.8Ć10²ⓠ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 1Ć10ā»ā“ is observed in the wire due to the motion of these particles?
