9. A CRT has an accelerating voltage of 15 KV, therefore electrons leaving the cathode would be going ______________m/s when they leave the E field. They travel a short distance and pass thru the deflection coils which produce a B field of 10 mT - which gives the electrons a bend radius of ___________m.

10. The B field is 4 cm long - they then travel 20 cm to a phosphorus screen. The dot on the screen is ______________m total off center
