Question

5. An electron moves with speed 5.0x10 m/s in a uniform magnetic field of strength 0.60 T that points East. At some instant, the electron experiences an upward magnetic force of magnitude 4.0x10 N. (a) In what direction is the electron moving at that instant? [Ifthere is more than one possible direction, describe all the possibilities.l (b) On a carefully drawn and labeled diagram, show the (possible) direction(s) of the electrons velocity relative to the magnetic field and the force directions. (Suggestion: Draw your diagram so that the force is perpendicular to the plane of the paper.) (c) What is the greatest force that this magnetic field could possibly produce on an electron moving at this speed? Show the orientation ofthat electrons velocity relative to the field.
