Question 4 of 10 - /10 E ... View Policies Current Attempt in Progress A source injects an electron of speed v = 1.2 x 10 m/s into a uniform magnetic field of magnitude B = 1.1 x 10-3 T. The velocity of the electron makes an angle 0 = 120 with the direction of the magnetic field. Find the distance d from the point of injection at which the electron next crosses the field line that passes through the injection point.
