A very long straight wire carries a current of 5 A. An electron moves with a velocity of 10⁶ m s⁻¹ remaining parallel to the wire at a distance of 10 cm from wire in a direction opposite to that of electric current. Find the force on this electron. (Here the mass of electron is taken as constant) e = -1.6 x 10⁻¹⁹C, μ₀ = 4π x 10⁻⁷SI.
