Document Summary
B q and b and b in the magnetic field b on the surface of the page). What is the direction of the magnetic force: negative charge q is moving with velocity v vectors v, parallel to v, parallel to b, exactly between v, into the page, out of the page. If the charge would be positive then from the right-hand rule follows that magnetic force is directed out of the page (rotate from v to b). F qvb: an electron is moving at speed v = 800 m/s. It enters a region with uniform electric field. 5 in a direction that is 30o to. Be v are perpendicular to each other. and. E = 400 v/m and uniform magnetic b field. What is the magnitude of the magnetic field b: 0. 5 t, 1. 0 t, 1. 5 t, 2. 5 t, 3. 0 t.
