A source injects an electron of speed v = 2.7 × 107 m/s into a uniform magnetic field of magnitude B = 2.7 × 10-3 T. The velocity of the electron makes an angle θ = 8.9∘ 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. Number Units
