An electron moving at 5.5 x 10m/s travels into a magnetic field that has a magnitude of 0.75 7. (Remember: me = 9.1 x 10-31 kg and e = 1.6 x 10-19 C.) (a) Calculate the magnitude and direction of the magnetic force on the electron. (b) Calculate the radius of the electron's circular path. Trace out this path (doesn't need to be to scale) (c) If a velocity selector with an electric field of 9.35 N/C [up] was positioned before the magnetic field shown below, what would the magnitude and direction of the magnetic field inside the selector need to be for the electron to pass through with its current velocity. O OO O OOOO electron ++++ ++ (d) A straight wire conductor with a current of 11A [left] is placed in the same magnetic field (B = 0.75 T) as shown below. How long would it take for the wire to travel at the same speed as the electron above if the wire has a linear density of 0.06kg/m. OOOO O O O
