A long straight wire suspended in the air carries a conventional current of 6.3 amperes in the -x direction as shown (the wire runs along the x-axis). At a particular instant an electron at location < 0, -0.003, 0> m has velocity < -2.5 × 105, -3 × 105, 0> m/s. (a) What is the magnetic field due to the wire at the location of the electron? B (0,0,4.2e-4) tesla (b) What is the magnetic force on the electron due to the current in the wire? F N (c) If the moving particle were a proton instead of an electron, what would the magnetic force on the proton be? F N z out
