A cylindrical conductor of length 2 m and area of cross-section 0.2 mm² carries an electric current of 1.6 A when its ends are connected to a 2 V battery. Mobility of electrons in the conductor is α × 10⁻³ m²/V·s. The value of α is : (electron concentration = 5 × 10²⁸ /m³ and electron charge = 1.6 × 10⁻¹⁹ C)
